GRIN Rod Lenses
Dec 2009Edmund Optics Inc.Request Info
Edmund Optics Inc.’s gradient index (GRIN) rod lenses feature plane optical surfaces and achieve focus using a continuous change of the refractive index within the lens material. The lenses eliminate complex geometries and provide a 0.55 numerical aperture. They are available in two working distance options. Lenses with a 0-mm working distance are suitable for collimation of single- and multimode optical fibers and laser diodes, while the small working distances are for focusing applications or situations where the lens cannot be in direct contact with the emission source.
