Keep NOA 148 in a cool (5-22 °C) dark place. If ref rigerated, allow the adhesive to come to room temperature before using.

Norland Optical Adhesive NOA 89 is a clear, colorless, liquid photopolymer that will cure when exposed to ultraviolet light and or visible light (blue-violet).

Aside of conventional Germanium window products, Hyperion Optics provides Ultra-thin germanium uncoated substrates for coating application. Upon custom requirement, we are able to fulfill as thin as 0.20-0.31 mm in center thickness, diameter as small as 3-5mm. Outer diameter special treatment is also available upon request, with extreme precise control of beveling <0.1mm for each face. Our Ultra-thin products are measured 100% individually to secure quality. Check our Ultra-thin category inventory list to match your potential demand.

NBA 107 is a single component, UV curing adhesive used for temporary bonding of lenses to metal polishing mounts or where bonded components need to be easily separated in the future.

In the range of 2-12 μm, germanium is the most commonly used material for the production of spherical lenses and windows for high efficiency infrared in imaging system. Germanium has a high refractive index (about 4.0 through 2-14μm band), usually do not need to be modified due to its low chromatic aberration in low power imaging systems. Hyperion Optics utilizes precision double polishers to produce Germanium windows at competitive pricing. We strictly control every critical parameter at different processing stages, such as surface accuracy and every physical dimension to meet tolerance requirement. We provide special power controlled windows i.e. one surface with low power, while polish the other side with high power ring. Please talk to one of our technicians for further information.

Adhesion is also good to cellulose acetate butyrate. NOA 148 is cured by ultraviolet light between 315 to 395 nm. Full cure requires 6 Joules/cm². The adhesive exhibits oxygen inhibition when used as a coating. To overcome this, the adhesive must be cured under an inert atmosphere, such as nitrogen.

Care should be taken in handling the this material. The material Safety Data Sheet should be read for this product. Prolonged contact with skin should be avoided and affected areas should be washed thoroughly with copious amounts of soap and water. If adhesive gets into eyes, flush with water for 15 minutes and seek medical attention.
