High Power Far Field Collimator
The optical fiber collimator (fiber collimator) is made from the precise positioning of the tail fiber and the lens. It can convert the transmitted light in the optical fiber into collimating light (parallel light), or parallel the outside world. (approximately parallel) light is coupled to a single-mode fiber. Through the lens, the optical fiber collimator can convert the beam with larger divergence angle (small beam waist) into one with smaller divergence angle (large beam waist). Thus, it is coupled into other optical devices with lower loss.
