    Fiber Collimator Single Fiber 850nm C-lens Gold-plated Tube Premium 5mm WD 250um 2M

     

    Fiber Collimators are devices used to expand and collimate the output light at the fiber end, or to couple light beams between two fibers. They are a module that combine a fiber and a lens, and has a function that produces parallel beams. When the fiber collimators are manufactured, the positions of the fiber and lens are adjusted so that parallel beams can be obtained, and this generally requires extremely fine adjustments. The more energy the fiber collimator is able to gather form the source and launch into the fiber end.They are available with different wavelengths (850 nm, 980 nm, 1060 nm, 1310 nm, 1550 nm) or fiber options (SM fiber, MM fiber, PM fiber, and LMA fiber, etc.).
