Focusing optical fiber collimator (focal length 4.5/7.5/11mm)


The design uses springs to assemble suitable optical lenses inside the mechanical parts, which can be used for the collimator output of optical fiber beam, and also for the coupling of optical fiber to optical fiber. By rotating the outer sleeve of the collimator, the inner optical lens can be translated forward and backward along the optical axis direction, so as to adjust the distance between the lens and the end face of the optical fiber and obtain different spot sizes.
