Micro Lens, Plano-Plano, Gradient Index, 1 mm, .46 NA,1300nm,0.25 Pitch

The LGI1300-2 GRIN Lens has a 0.25-pitch lens that is useful for fiber coupling and collimating and fiber-to-fiber coupling. This SELFOC® radial gradient index oxide glass general purpose plano-plano lens has a 1.0 mm diameter, a 2.63 mm length, a 0.46 NA, and is antireflection coated to provide maximum transmission at 1300 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.
