Lensed Fiber Introduction
Lensed Fiber, is also named as fiber micro-lens or fiber lens. It is used to change light path or mode conversion in light system by special process on optical surface of fiber. According to different applications, we have three types of lensed fiber. They are: Cylindrical Lensed Fiber, Spherical Lensed Fiber and Collimated Beam Lensed Fiber.
1. Spherical Lensed Fiber
Introduction: Polish spherical shape on the optical surface of fiber, to enlarge fiber NA by special process on the fiber tip.
Feature: High Coupling Efficiency; Simplicity and Reliability.
Application: LD,DFB,SLD Laser or VCSEL Coupling; Medical Laser and Lighting.
2. Cylindrical Lensed Fiber
Introduction: Most of cylindrical lensed fiber assemblies is used for light patch coupling. There are several processing techniques, micro-cylindrical lensed fiber processing, side-cylindrical lensed fiber processing, three-cylindrical lensed fiber processing, four-cylindrical lensed fiber processing and so on.
Feature: High Coupling Efficiency for Elliptical FFP
Application: Assembly for 980nm LD; Optical Direct Coupling to LD or Wave Guide.
3. Collimated Beam Lensed Fiber
Introductoin:Lapping a ball on the optical surface of fiber, polish customized angle and size.
Feature: Small size Collimator Monolithic Collimator
Application: Fiber Collimator Optical Switch, Filter Module, PD Module, etc. Optical Sensor
