G-lens (grin lens) for collimator,fiber coupler

タイトルまたは説明

GRIN lenses are used to focus and collimate light within a variety of fiber optic components. GRIN lenses , short gradient index, focus light throough a precisely controlled radial varition of the lens material index of refraction from the optical axis to the edge of the lens. This allows a GRIN lens with flat or angle polished surface to collimate light emittied from an optical liber or to focus an 
incident beam into an optical liber. End faces can be provided with an anti-reflection coating to avoid unwanted back reflection.
GRIN lenses can be used for WDM Collimater, Optical Switch,Attenuators and Fiber to fIber couping systems.
