Adhesives for Laser Device Manufacturing

Model Solid Refractive Index Viscosity Features
NOA61 1.56 300cps Military-grade optical adhesive, low shrinkage, for optical systems exposed to very low temperatures; meets MIL-A-3920; widely used in the optics industry.
NOA68 1.54 5000cps Medium-viscosity UV-cure adhesive, low shrinkage, flexible; ideal for fiber fixing.
NOA83H 1.56 300cps UV/heat dual cure, low shrinkage, wide temperature resistance.
NOA1369 1.382 2100cps Low-refractive-index UV adhesive, medium viscosity, for double-clad fiber and laser-power fiber coating.
NOA13775 1.391 4000cps Low-refractive-index UV adhesive, high-temperature resistant, for double-clad fiber recoating; replaces PC373 etc.
NEA123HGA NA 300Kcps High-viscosity low-outgassing UV/heat dual-cure adhesive for laser device packaging; also for fast tacking, filling, sealing and bonding precision parts or wires.
NEA123SHGA NA 60Kcps Low-outgassing high-viscosity UV/heat dual-cure adhesive for fast tacking, filling, sealing and bonding precision parts or wires. Besides UV cure, NEA123SHGA contains a latent heat catalyst that quickly cures areas UV cannot reach.
