Four-Faceted Lensed Fiber / Pyramidal Lensed Fiber

A Lensed Fiber is produced 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 meets specific requirements for optical path, spot size, and coupling efficiency. Based on diverse client needs, Feiyi Photonics fabricates various lensed fibers with specialized end-face geometries and can deposit optical coatings upon request, providing fully customized optical solutions.
