What are gradient index (GRIN) lenses?
Gradient Index (GRIN) Lenses are high precision cylindrical lenses with comparable performance to conventional aspherical singlet lenses, but feature plano (flat) optical surfaces.
Why are gradient index (GRIN) lenses innovative?
Gradient Index (GRIN) Lenses achieve focus via a continuous change of the refractive index within the lens material. By eliminating complex geometries (such as aspherical surface figures) and carefully designing the lenses for specific working distances, these micro lenses are quite easy to handle and integrate into optical systems.
In what applications are gradient index (GRIN) lenses used?
Gradient Index (GRIN) Lenses are ideal for collimation of single and multi-mode fiber optics and laser diodes because they can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lenses cannot be in direct contact with the emission source, all lenses are available with a small working distance as well.
