The basic principle of optical fiber collimator is to place the fiber end face at the focal point of the collimating lens to collimate the beam, and then slightly adjust the position of the fiber end face near the focal point to obtain the required working distance, so the working.

Hobbite provides high-performance fiber collimators, regarded as “beam-shaping experts. ” They convert divergent light emitted from fibers into collimated beams or focus parallel beams into fiber cores, ensuring stable and high-quality signal transmission. They can also be used in reverse to focus light into a fiber. In essence, a simple collimation lens is all that is needed for this purpose. A fiber collimator changes light from a fiber into a straight, parallel beam.
