Lensed Fiber

Lensed Fibers are required for the manufacturing of Butterfly Type and Optical Pump Modules. By our processes of discharging, etching, lapping, polishing and grinding the end face of the fiber, we can configure the Lensed Fiber form similar to an actual lens shape suitable for connection and improved coupling efficiency with LD and PD Modules.

We have several lens fiber types, CLF (Cylindrical Lensed Fiber) and SLF (Spherical Lensed Fiber) and we can also combine the process to include Metallization, AR-Coating, Metal Tube and FBG with the lensed fiber assembly.

All of our Lens Fibers are custom products designed per customer specification requirements and processed based on our extensive experience resulting in an optimum design to fulfill your needs.
