GRIN Lens
Gradient Index (GRIN) Micro Lenses are
widely used in fiber optics for collimating light from fiber, focusing light to fiber, or
coupling light between fiber and LD/LED/Detector/Fiber. CASIX has large capability in
fabricating (polishing and AR-coating) high quality GRIN lens based on customers's
requirements. OEM parts with different pitches, wedges, coatings as well as top flats are
welcome.
