Wedge Lensed Fiber
A Lensed Fiber is manufactured by precision processing the optical fiber endface into multiple facets or a conical shape, with the core region at the tip finished as a flat or spherical surface. This specialized design meets specific requirements for optical path, spot size, and coupling efficiency. Catering to diverse client needs, Feiyi Photonics can fabricate various lensed fibers with specialized endface geometries and can deposit optical thin films upon request, offering fully customized optical solutions.
