Norland Optic Adhesives are clear, one part adhesives that contain no solvents. When exposed to UV light, they gel in seconds and cure fully in minutes to give a tough resilient bond. Each of the six formulas listed below has been optimized to provide excellent bonding for specific applications. To cure these optical adhesives, they must be exposed to UV light.
Shelf Life
These UV-curing adhesives have a shelf life of approximately 8 months. This time frame begins on the date the epoxy was packaged at the manufacturer. Upon receipt by the end user, Thorlabs guarantees that the remaining shelf life will be at least 3 months.

| NOA60 (Only Available in K6-NOA KIt) |
|
NOA60 typically has three uses: as a mounting cement for lenses, for the assembly of doublets or prisms, or for mounting components between two pieces of glass or plastic. Due to its excellent insulating properties, NOA60 can also be used as a protective overcoat on electrical components. The cured polymer has an refractive index of 1.56 Please note that the NOA60 is only available in the K6-NOA kit. Please contact us for a quotation and MSDS.Contact Us |

| NOA61 |
|
NOA61 is designed to give the best possible bond to glass surfaces and may be polished after curing. It meets Federal Specification MIL-A-3920 for optical adhesives and is approved for use on all government contracts specifying such adhesives. This adhesive has excellent adhesion to metal, fiberglass and glass-filled plastics. The refractive index of the cured polymer typically has a value of 1.56. | ||||||
| NOA63 |
|
NOA63 can be used for bonding achromats, prisms and all other precision compound optics. The characteristics of this adhesive are its low fluorescence and its excellent transmission in the UV range. This adhesive is also suitable for bonding glass to metal. The adhesive cures well in thick sections and has a slight resiliency to minimize strain. The refractive index of the cured polymer typically has a value of 1.56. | ||||||
| NOA65 |
|
NOA65 when cured is a very flexible adhesive and minimizes strain. It is suitable where the adhesive cross section would be relatively thick. It has enough elasticity to minimize strain even when materials with different coefficients of expansion are bonded. It is used for potting of lenses in metal mounts and bonding plastic to glass. It is also a blocking cement for temporary mounting on polishing blocks. The refractive index of the cured polymer is 1.52. | ||||||
| NOA68 |
|
NOA68 is a flexible adhesive designed to give improved adhesion to many plastics such as acrylic, polycarbonate and CAB. Suggested uses for NOA68 include bonding compound plastic lenses, laminating polarized film between glass or plastic, mounting lenses in metal or plastic mounts and bonding cover glasses onto plastic optics. The refractive index of the cured polymer typically has a value of 1.54. | ||||||
| NOA81 |
|
NOA81 is an extremely fast curing adhesive. NOA81 has similar qualities to the NOA61, yet it can cure 3 to 5 times faster. However, curing times are dependent on the UV light source. Not only is it a faster curing adhesive, it is also tougher and stronger. NOA81 is recommended for applications that require extra toughness or speed in curing. The refractive index of the cured polymer typically has a value of 1.56. Like NOA61, it may also be polished. | ||||||
| K6-NOA | The K6-NOA kit includes all six of the NOA UV curable optical adhesives above together with application data on each of the adhesives. The kit does not include the NBA107 block adhesive for temporary bonding of glass to metal. | |||||||
| NBA107 | NBA107 is a single component, UV curable adhesive used to temporarily bond optical components to metal polishing fixtures. The adhesive cures by exposure to UV light, thus eliminating the heat induced strain typically of hot pitch mounting methods. Deblocking, or removal of the optic is accomplished by immersing the bonded optic in warm (80 °C) water. The refractive index of the cured polymer typically has a value of 1.51. | |||||||
