Principle of Multimode Fiber Collimator

Home / Principle of Multimode Fiber Collimator

A fiber collimator changes light from a fiber into a straight, parallel beam. 1 This animation provides an introduction to the mechanism of the FiberPort and shows how the FiberPort can be used as a collimator. The beam diameter Ø beam is given by the focal length of the collimating lens f' and by the numerical aperture NA of the multi-mode fiber. " They convert divergent light emitted from fibers into collimated beams or focus parallel beams into fiber cores, ensuring stable and high-quality signal transmission.
