Collimators are required to generate a parallel beam of light out of the naturally diverging light emission from an optical fiber. Most standard fiber optic collimators are designed for low NA or thin fibers, and cannot efficiently be collimated with High NA fiber such as Polymer Optical Fibers (POF) without a great reduction of output power.
The Custom Prizmatix Half Inch Collimator is designed to work with 2mm LLG providing an efficient solution to this problem
