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.

NOA60 is typically used as a mounting cement for lenses, for the assembly of doublets or prisms, or for mounting components between a sandwich of glass or methacrylate plastic. Because of its excellent insulating properties, NOA60 can also be used as a protective overcoat on electrical components.

NOA61 is designed to give the best possible bond to glass surfaces. 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.

NOA63 can be used for bonding achromats, prisms and all other precision compound optics. The outstanding 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 low shrinkage and a slight resiliency to minimize strain.

NOA65 when cured is a very flexible adhesive and was designed to minimize strain. NOA65 is especially suitable where the adhesive cross section would be relatively thick. NOA65 has enough elasticity to keep strain to a minimum even when dissimilar materials, with different coefficients of expansion, are bonded together. Typical applications would be potting of lenses in metal mounts and bonding plastic to glass. Also suitable as a blocking cement for temporary mounting on polishing blocks.

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.

NOA81 is an extremely fast curing adhesive. NOA81 has similar qualities to the NOA61, yet it can cure 3 to 5 times faster. 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.

K6-NOA kit includes all six 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 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.

For curing the optical adhesives above Thorlabs offers a UV curing system with an intensity of 600 mW/cm2.
