Plano-Plano Gradient Index Micro Lens, 1.8mm, .46 NA,1560nm,0.23 Pitch

The LGI1560-1A has a 0.23 pitch lens that is useful for collimating laser diodes and non-contact fiber coupling and collimating. To reduce back reflections, this SELFOC® radial gradient index oxide glass, plano-angled lens has one 8° angled face. It has a 1.8 mm diameter, a 4.43 mm length, a 0.46 NA, and is antireflection coated to provide maximum transmission at 1560 nm. Gradient index micro lenses have a radially varying index of refraction that causes an optical ray to follow a sinusoidal propagation path through the lens. They combine refraction at the end surfaces along with continuous refraction within the lens.
