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.
Polish spherical shape on the optical surface of fiber, to enlarge fiber NA by special process on the fiber tip.
High Coupling Efficiency;
Simplicity and Reliability.
LD、DFB、SLD Laser or VCSEL Coupling;
Medical Laser and Lighting.
