Micro Optics >> GRIN-LENS

Grin-lens are specifically designed for fiber optics applications, also named as graduated refractive index rod lens. That means different layer in the rod lens has different refractive index. It can can collimate, focus and form a image on the physical surface of a lens. Grin-lens is widely used in many passive components( collimaor, coupler, isolator, circulator, WDM and etc).
