UV Cure Optical Epoxy

EPO-TEK® OG142-112 Advantages & Suggested Application Notes:● Semiconductor: glob top “fill” encapsulant over IC’s and wire bonds. It can be potted into cavities or around diethat utilize a dam or ring.
● Fiber Optic:◊ Securing fibers into V-grooves; mounting glass cover slip over v-groove arrays; adhesive for fiber/ lens arrays.
◊ Adhesive for the PLC device onto optical bench.
◊ Fiber splicing, coupling and joining. Active alignment of optics into package.
● Optics:◊ Adhesion to all types of glasses, Lexan polycarbonate, and many more plastics and laminates.
◊ Adhesive in the beam-pathway; capable of transmitting light from 400 to 2000 nm range.
◊ Bonding beam splitter cubes and prisms together.
◊ Adhesion to micro molded lenses.
● Potting:◊ Sealing and weather-proofing the solar ribbon connections to the environment via glass framed CIGS PVmodules.
