The post ThorLabs 1″ (25 mm) Travel Dovetail Translation Stages, Vacuum-Compatible appeared first on Politek Vietnam Import Export Services Trading Company Limited.

Features

• 1″ (25 mm) Travel
• Vacuum Compatible Down to 10^-6 Torr
• Array of 13 1/4″-20 (M6 x 1.0) Tapped Holes
• XYZ Configurable Using DTSA03V(/M) Angle Bracket
• Mounted to Optical Table Using 1/4″ (M6) Counterbores or CL6V Table Clamps (Sold Separately)

The DTS25V(/M) dovetail translation stage is a vacuum-compatible, compact positioner for use in general purpose motion control applications. It provides a travel range of 1″ (25 mm) using a precision-rolled M6 x 1.0 mm pitch leadscrew for smooth linear positioning along the entire range of travel. The stage is advanced 0.04″ (1.0 mm) for each full revolution of the leadscrew. The top surface of the DTS25V(/M) stage is equipped with an array of thirteen 1/4″-20 (M6 x 1.0) tapped holes to maximize the mounting options for moving components. This moving platform is lockable via a side-located screw in a locking bracket to guard against accidental movement. A scale with 1/40″ (1.0 mm) graduations is etched onto each side of the moving platform, with the edge of the locking bracket providing a reference for relative positioning, shown to the in Figure 1.1.
	Figure 1.1  The DTS25V(/M) comes with a side locking plate that can be used to prevent accidental movement and as a relative positioning reference.
Mounting Options The stage can be bolted directly to the optical table using four counterbored 1/4″ (M6) holes that are revealed by translating the top plate of the stage to the proper position. Two of these mounting holes are accessed via clearance holes in the top plate, while the other two are directly accessible. Alternatively, the stage can be mounted using four CL6V clamps (two on each side) secured to the relief cut along the bottom of the stage, as shown in Figure 1.2.
	Figure 1.2  The DTS25V/M stage is mounted to an MB6S vacuum-compatible breadboard using vacuum-compatible table clamps and screws.

Multi-Axis Configurations
The modular design of the DTS25V(/M) allows the stages to be configured easily into 2- and 3-axis configurations. Two dowel pins are included with each stage, and these can be used to ensure that orthogonality between the various translation directions is maintained during construction. In order to construct an XY configuration, two stages can be directly connected. For movement in the Z direction, the vacuum-compatible DTSA03V(/M) angle bracket is required to mount a stage vertically. The bracket can be attached to a horizontal stage or optical table using four 1/4″ (M6) counterbores and a stage can then be mounted vertically using four of eight 1/4″-20 (M6 x 1.0) tapped holes on the side of the bracket.

Vacuum Compatibility
The DTS25V(/M) stage is designed using vacuum-compatible materials allowing it to be used at pressures down to 10^-6 Torr and maintain the same performance as the DTS25(/M) dovetail translation stage. Each DTS25V(/M) stage is assembled in a clean environment and double vacuum bagged. Prior to use in a vacuum system, the stages can be baked to remove excess moisture and surface contaminants; however, please note that the maximum baking temperature is 130 °C. The stage can be mounted to a breadboard using Thorlabs’ CL6V vacuum-compatible clamps and vacuum-compatible fasteners, shown in Figure 1.2. Thorlabs offers vacuum-compatible breadboards, screws, and other optomechanics that can be can be used with the stage.

These kinematic positioners can be used individually or in functional groups for a variety of quick breadboard positioning and adjustment applications. The simple design and low cost make these mounts perfect alternatives for optomechanical positioning requirements when a precision translation stage is not necessary.

Insights into Best Lab Practices

Scroll down to read about a practice we follow when setting up lab equipment.

Washers: Using Them with Optomech

The head of a standard cap screw is not much larger than the major diameter of the thread (Figure 1). For example, a 1/4″-20 screw has a head diameter between 0.365″ and 0.375″ and the clearance hole diameter for the threads is 0.264″. When the screw is tightened directly through the clearance hole to secure the device, the force is applied to the edge of the through hole, often cutting into the material (Figure 1). Once the material is permanently deformed, the screw head will want to fall back into the gouged groove, thereby moving the device back to that location when attempting to make fine adjustments. A device with a circular through hole is not meant to translate around the screw thread so the deformation is not expected to be a problem. However, a slot should provide the ability to secure the device anywhere along the length for the lifetime of the part. Using a washer distributes the force away from the slot edge to decrease the chance of deforming the slot and extending the lifetime of the part. Figure 1 illustrates the difference a washer can make. The contact area between the slot of a BA2 base and a 0.27″ diameter cap screw is 0.010 in2. When a 0.5″ diameter washer is used the contact area is 0.064 in2, which is over six times larger. When using a Thorlabs washer, there are two distinct sides (Figure 2). One side is flat and rough and the other is curved and polished. The curved and polished side should be placed against the device, which has an anodized surface. As the screw tightens, the screw head can force the washer to spin against the anodized coating. If the flat side is pressed down against the anodization, the friction created by the rough flat side can scratch the anodized aluminum. However, if the curved side is facing down, the smooth surface has less friction leading to less scratches and extending the visual appearance of the device.
	Figure 1: The diameter of the washer is 35% larger than that of the bolt head. This results in over a six fold increase in overlap area with the slot of a BA2 base. By distributing the force of the bolt over a larger area, the washer help prevent gouging of the slot.
	Figure 2: Install washers before inserting bolts into slots to protect the slot from damage. The rounded, smooth side of the washer should be placed against the slot, and the rough, flat side should be in contact with the bolt head. The smooth surface is designed to translate easily across the anodized surface, without harming it. The BA2 base is illustrated.

ThorLabs Kinematic Platform Positioners

Fixed Kinematic Stops

Use as a Stop or Reference Edge Hardened Steel Ball for One-Point Contact 0.74″ (18.8 mm) or 1.50″ (38.1 mm) Long Slot for 1/4″-20 (M6) Cap Screws Our Fixed Kinematic Stops can be used alone, in pairs to define a reference edge, or as a group of three to define a reference edge and stop. Each stop has a hardened steel ball for a true one-point contact on one end and a base that is machined with a wide, bottom-located relief cut for stable positioning when mounting to an optical table. The KL01 is convenient to use in space constrained applications because it has a smaller slot and more compact design. The KL01L has a longer slot, capable of spanning two tapped holes at a 45 degree angle on an optical table. This allows the KL01L to be secured to a table using two cap screws, providing more stability and resistance against rotation in a system. As shown in Figure G1.1, the fixed kinematic stops are useful in repeatable positioning when swapping a base plate or breadboard in and out of an optomechanical setup. Our kinematic stops maintain the position of an MB8 Breadboard with DF1 Low-Friction Feet. To match the height of the breadboard and low-friction feet, each stop is mounted on a BA2S6 Spacer. A KL01 and KL01L are used to define a line on one edge of the breadboard, while one KL01 acts as a stop for the perpendicular edge of the breadboard. Thus, the breadboard can be removed from its position and returned with good repeatability.
	Figure G1.1  Breadboard with DF1 low-friction feet. The KL01 and KL01L kinematic stops preserve breadboard location.

Base Position Retainers

Mark the Position of Bases within an Optical System Realignment Based on Three Contact Points Swivel Head Retainer Available with 200° of Rotation Thorlabs’ Position Retainers can be used to realign bases and other squared-off components that have been removed from an optical system. They act as markers on the breadboard or optical table in the event that you need to remove a component from your setup. The three white dots engraved on the surface of the retainer mark the three points that contact your part. The RSPCS(/M) Swivel Retainer features a swivel head for 200° of rotational adjustment. This enables users to save the arbitrary position and angular rotation of squared-off optomechanical components. To achieve this, the component should be independently locked before aligning the three dots on the RSPCS(/M) to the corner of the component. Partially loosen the tension adjuster screw and then mount the retainer to a breadboard tap while maintaining contact with all three points. Lastly, tighten the tension adjuster screw. After this the component can be removed from the setup and then later placed back into the same position. The RSPC Fixed Retainer is a compact solution for situations where a tapped hole is diagonally positioned from the base, as shown in Figure G2.2. As with the RSPCS, the component should be independently locked before aligning the RSPC retainer. After the retainer is mounted in place, the component can be removed from the setup and then later placed back into the same position. The RSPC Retainer can also be secured to an optical table or breadboard via the CL6 clamp. This clamp is useful in situations where the RSPC cannot be placed directly over a hole in the table.

Adjustable Kinematic Positioner, 1/'' (M6) Counterbore

Fine Position Control via 120 TPI Fine Hex Adjuster Maximum Travel Range: 0.96″ (24.4 mm) Side-Located Counterbore for 1/4″ (M6) Cap Screws Facilitates Mounting to a Breadboard or Base Flexure Clamp Attaches to Either End of a Ø1/2″ Post The APM05(/M) Adjustable Kinematic Positioner allows for the precise positioning of breadboards or optomechanics. It contains a high-precision 3/16″-120 hex adjuster (Item # F19MS150) that has a maximum axial load capacity of 5 lbs (2.3 kg). It can be actuated using a 5/64″ (2 mm) hex key, providing fine positioning. If longer or shorter translation ranges are required, the adjuster can be replaced with any other 3/16″-120 hex adjuster. A side-located 1/4″ (M6) counterbore allows the adjuster to be attached to a breadboard, base, or to the 1/4″-20 (M6) end of a Ø1/2″ post using a 1/4″-20 (M6) cap screw. In addition, it can be mounted to a Ø1/2″ post using a bottom-located flexure clamp, which is tightened using a side-located cap screw and a 9/64″ (3 mm) hex key. When mounted via the flexure clamp, the adjuster will be centered on top of the post. In contrast, when mounted using the side-located counterbore, the adjuster will be offset to the side by 0.40″ (10.2 mm). This adjuster can be used with any 1/4″-20 (M6) tapped optomechanics or tables, as shown in Figure G5.1. The photo shows the APM05 used in combination with two KL01 Stops and one KL03 Spring-Loaded Plunger to adjust the position of a UBP2 Universal Base Plate along a straight line.

Adjustable Kinematic Positioner, 1/4'' - 20 (M6) Tapped Holes

Fine Position Control via 120 TPI Fine Hex Adjuster Maximum Travel Range: 0.66″ (16.76 mm) Two 1/4″-20 (M6) Taps for Attachment to Bases or Ø1/2″ Posts The APM07(/M) Adjustable Kinematic Positioner allows for the precise positioning of breadboards or optomechanics. It contains a high-precision 3/16″-120 hex adjuster (Item # F19MS150) that has a maximum axial load capacity of 5 lbs (2.3 kg). It can be actuated using a 5/64″ (2 mm) hex key, providing fine positioning. If longer or shorter translation ranges are required, the adjuster can be replaced with any other 3/16″-120 hex adjuster. The positioner features two 1/4″-20 (M6) taps for mounting. This adjuster can be used with optomechanics that offer 1/4″-20 (M6) taps at 1″ (25 mm) spacings. Figure G6.1 shows the APM07 used in combination with two KL01 Stops and one KL03 Spring-Loaded Plunger to adjust the position of an aluminum breadboard along a straight line. Figure G6.3 shows the APM07 mounted on a 34 mm Rail using an XT34D2-50 Mounting Platform to provide positional adjustment of rail-mounted optomechanics. Alternatively, this adjuster can be mounted on a Ø1/2″ post using a 1/4″-20 (M6) cap screw or setscrew as shown in Figure G6.2. The photo shows the APM07 used with the APM06 Spring-Loaded Plunger to adjust the position of a lens mounted on the KMCP Centering Plate. The adjuster will be offset from the center of the post by 1/2″ (12.7 mm) making it ideal for setups on Double Density Breadboards.

Spring-Loaded Plungers

High-Strength, Spring-Loaded, Plastic Plunger Travel Range: 0.25″ (6 mm) 0.85″ (21.6 mm) or 1.50″ (38.1 mm) Long Slot for 1/4″-20 (M6) Cap Screws Our Spring-Loaded Plungers can be used to hold an object firmly against Kinematic Stops or an Adjustable Positioner. The high-strength plastic plunger on both the KL03 and KL03L applies spring pressure over a travel range of 0.25″ (6 mm). The plunger tension can be adjusted using a 5/32″ (4.0 mm) hex key. The KL03 is convenient to use in space constrained applications because it has a smaller slot and more compact design. The KL03L has a longer slot, capable of spanning two tapped holes at a 45 degree angle on an optical table. This allows the KL03L to be secured to a table using two cap screws, providing more stability and resistance against rotation in a system. In Figure G3.1, one KL03 plunger is used with two KL01 kinematic stops while one KL03L plunger is used with a KL02 adjustable positioner to translate a BA2 base back and forth along a line. On one side of the base, two KL01 stops define a reference edge. On the opposite side, the KL03 presses the base against the two stops and prevents it from moving in the direction perpendicular to the reference edge. Along the other edges, the KL03L plunger presses against a KL02 adjustable positioner. Without the KL03L, the KL02 could only push the base forward. However, in this setup, as the KL02 is retracted, the KL03L provides an opposing force that pushes the base back.
	Figure G3.1  A KL03L plunger is used to provide an opposing force against the KL02 positioner, such that turning the KL02’s adjuster can move the BA2 base forward or backward, as indicated by the arrows.

Adjustable Kinematic Positioners, 0.40'' (10.16 mm) Travel

Fine Control of Positioning Travel Range: 0.400″ (10.16 mm) 0.85″ (21.6 mm) or 1.50″ (38.1 mm) Long Slot for 1/4″-20 (M6) Cap Screws Our Adjustable Kinematic Positioners provide the same spherical contact as the Fixed Kinematic Stops presented above but adds fine adjustment capability with a 1/4″-80 actuator used as a “nudger.” This feature allows for precise positioning not achievable by hand. These kinematic positioners are ideally used with two KL01 or KL01L stops to define a reference edge for a translation path. The KL02 is convenient to use in space constrained applications because it has a smaller slot and more compact design. The KL02L has a longer slot, capable of spanning two tapped holes at a 45 degree angle on an optical table. This allows the KL02L to be secured to a table using two cap screws, providing more stability and resistance against rotation in a system. In Figure G4.1, a KL02L kinematic positioner is used to nudge a BA2 base forward along a line. The line is defined by two KL01 stops which are positioned on one side of the base. A plunger on the opposite side of the base ensures that the base stays against both fixed kinematic stops while sliding forward.
	Figure G4.1  A KL02L adjustable kinematic positioner is used to finely nudge forward a BA2 base held by two KL01 kinematic stops and one KL03 plunger. The arrow indicates the direction of motion.

These differential adjusters are designed for use on stages with a 9.5 mm (3/8″) mounting clamp. The DRV304 is ideal for updrading our RB13M 3-axis ollerBlock stage to differential drives. The DM10 is for use with our MT1 and MT3 stages.

See the presentations below for more details.

Manual Drives, 1/2″ Differential Micrometer Designed for Use with Our RollerBlock Stages Coarse Adjustment: 1/2″ (13 mm) Travel, 0.5 mm per Revolution Coarse Resolution: 5.0 µm Fine Adjustment: 300 µm Travel, 50 µm per Revolution Fine Drive Resolution: 0.5 µm The DRV304 Differential Micrometer uses a unique mechanism that converts a relatively large displacement into a relatively small displacement of the center fine adjustment spindle. The design has the additional benefit of providing a uniform, smooth feel that is largely independent of loading. Coarse adjustment is provided via a knurled knob, while the differential adjuster features a large rubber grip which adds to the overall sensitivity of the unit. The coarse adjustment knob gives 1/2″ (13 mm) of total travel with 5.0 µm resolution, while the differential knob provides 300 µm of total travel with 0.5 µm resolution. The Ø3/8″ mounting barrel is compatible with a host of standard mounting equipment.

Manual Drives, 1/2″ Differential Adjuster Designed Specifically for Use in Our 1/2″ Travel Stages Coarse Adjustment: 1/2″ (12.7 mm) Travel, 0.5 mm per Revolution Fine Adjustment: 250 µm Travel, 25 µm per Revolution The DM10 Differential Adjuster uses two internal leadscrews; one pushes the center spindle forward at 400 µm per revolution, and one pulls it back at 375 µm per revolution. The resultant total forward motion of the center spindle is just 25 µm per one complete revolution of the graduated knob. For more details on the operating mechanism of the DM10, please refer to the DM10 Operation tab. Each graduation of the fine control knob is 0.5 µm. The coarse adjustment provides 1/2″ of travel with a screw pitch of 0.5 mm, which is lockable via a thumbscrew located on the mounting barrel. If the fine adjustment knob on the DM10 is ever removed from the actuator body, it can be reattached. Please see the DM10 Knob Attachment tab for more details. Follow the reattachment instructions carefully so that the actuator functions properly. If a longer travel range is needed we also offer our DM12 1″ Differential Adjuster.

Features

• Break-Over Design Ensures Proper Mating Torque is Supplied
• Preset Torque Values Prevent Over-Tightening
• Each Torque Wrench Engraved with Preset Torque Value, Torque Direction, Wrench Size, and Item #
  • Serial Number Engraved on TQW4A, TW6, TW13, and TW18 Torque Wrenches

Thorlabs’ Torque Wrenches provide preset torque values to secure either coaxial connectors or Polaris lock nuts. When the preset torque value has been achieved, the break-over design will cause the pivoting joint to “break,” as shown in the image above. This will prevent further force from being applied to the connector. The wrench’s hex head will move back into place once the force is removed.

• Preset Wrenches for Coaxial Connectors (See Table G1.2 for Compatibility):
  • TQW4A: 6 mm Hex, 4 lb-in Torque
  • TQW5A: 5/16″ Hex, 5 lb-in Torque
  • TQW8A: 5/16″ Hex, 8 lb-in Torque

These torque wrenches have a preset torque value to ensure that the proper amount of torque is supplied when mating two coaxial connectors. The TQW4A is set to provide 4 lb-in of torque, which is ideal for 1.0 mm connectors; the TQW5A is set to provide 5 lb-in of torque, which is ideal for most SMA connectors; and the TQW8A is set to provide 8 lb-in of torque, which is ideal for 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm, K, and V connectors.

When the preset torque value has been achieved, the break-over design will cause the pivoting joint to “break”, as shown in the image above. This will prevent further force from being applied to the connector. The wrench’s hex head will move back into place once the force is removed. The torque wrench should be held at the load-point line inscribed near the end of the handle; holding the handle at a different location will affect the amount of torque applied to the connector. The specified torque is guaranteed only when tightening in the direction indicated by the arrow engraved on the handle. Each wrench is also engraved with its preset torque value, torque direction, wrench size, and Item # for easy identification in the field; the TQW4A also includes an engraved serial number.

The preset torque value for each wrench is guaranteed for one year from the date of purchase. If necessary, wrenches may be returned to Thorlabs for recalibration; please contact US for details.Contact Us

Features

• C-Band Amplification in 1550 nm Range
• Polarization-Dependent and Independent Versions
• Integrated Current Driver for High-Speed Switching
• Turnkey Operation with Temperature Control

Thorlabs’ HS Series High-Speed Optical Amplifier Instruments integrate high-speed drivers and polarization-independent semiconductor optical amplifiers (SOAs) or polarization-dependent booster optical amplifiers (BOAs) to provide turnkey solutions for high-speed switching. These instruments provide high extinction ratios of 70 dB, ideal for optical shutter or switching applications.

Switching and pulsing operation is controlled through the TRIGGER INPUT port of this high-speed optical amplifier. Trigger mode options are continuous drive current (CW), Hi-Z for low-frequency operation (<1 MHz), and both AC- and DC-coupled 50 Ω triggering for high-frequency operation (>1 MHz). Output gain is produced by a variable current source, adjustable with discrete settings. With a high-speed, user-supplied trigger signal, switching speeds of <1 ns can be achieved using the input voltages specified in Table 2.3 on the Specs tab.

The drive electronics, temperature control circuits, and safety interlocks for these amplifier instruments are integrated into each device and are powered by an included DS15 power supply with a region-specific plug. Two FC/APC connectors serve as the fiber input and output ports for integration into fiber-terminated systems. Thorlabs stocks a variety of FC/APC terminated SM and PM fiber patch cables that may be used alongside these instruments.

Gain Control
The gain for these amplifier instruments is controlled by adjusting the drive current in discrete steps, which are optimized for the individual device. The drive current selector on the back panel can be set to one of 16 positions using the included 2.5 mm screwdriver. When set to the MAX position, the typical operating current for each device will allow for the maximum output power to be achieved.

Triggering
Switching operation for these amplifier instruments is controlled by a user-provided electrical waveform, via the female SMA Trigger port on the back panel. For example, this device can produce an optical pulse from a user-supplied electrical pulse.

Four trigger mode options are available: continuous drive current (CW), Hi-Z suggested for low-frequency operation (<1 MHz), 50 Ω AC, or 50 Ω DC (with the last two options coupled for high-frequency operation greater than 1 MHz). The trigger mode control, located on the back panel, allows for the selection of each of these trigger modes.

Additional Front & Back Panel Features
A dual-color (red/blue) emission indicator LED on the front panel indicates when laser output is enabled and is designed to be visible through most laser safety glasses.

In addition to the trigger port, trigger mode control, and drive current control, a dual-color (red/green) status LED on the back panel indicates the operation state, including temperature stabilization and any errors. An engraved reference for the trigger mode options is also provided. Please see the Front & Back Panels tab and manual for more details about these features.

The HS series amplifiers have built-in safety features including a key switch, interlock pin, and a four-second delay between the emission LED illuminating and amplifier output.

The trigger mode control, located on the back panel, allows for the selection of each of these trigger modes.

• Polarization-Dependent and Independent Versions
• Fiber Pigtails with FC/APC Connectors
• Case Temperature Control via Internal Thermoelectric Cooler (TEC) Element

Thorlabs’ High-Speed Optical Shutters/Switches are designed specifically for applications requiring an optical shutter with operation around 1550 nm. All our optical switches provide an extinction ratio greater than 60 dB. The devices are based on our semiconductor amplifier platform consisting of a highly efficient InP/InGaAsP Multiple Quantum Well (MQW) layer structures grown on an InP wafer and processed into a proven and reliable ridge waveguide. The device can operate as a lossless, high-speed, optical isolation switch, a full-range variable optical attenuator (VOA), or an optical shutter for protection of delicate optical equipment.

Mount and Driver Options
These butterfly packages are compatible with the CLD1015 laser diode mount with integrated controller and TEC, however, this controller will only be able to achieve switching speeds of around 4 µs. They are also compatible with the LM14TS and LM14S2 mounts, which can be used with our laser diode, TEC, and combined current/TEC controllers. When operating these lasers in environments with more than 5 °C variation in temperature, we recommend using the LM14TS mount, which provides active control of the butterfly package’s case temperature to stabilize the amplifier’s output wavelength and power. For information on compatible drivers that can achieve switching times up to the specified 1 ns time scale, please contact USContact Us
