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.

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.
