Description
It is engineered with a spring-fitted optical lens housed within its mechanical structure. It serves to collimate the fiber-emitted light beam and can also be utilized for coupling spatial light into the fiber. By rotating the outer sleeve off the collimator, the internal optical lens can be precisely translated along the vertical axis direction. This translation enables the adjustment of the distance between the lens and the fiber end face, thereby achieving different light spot sizes. Once the optimal position is attained, the housing knurled locking ring can be employed to fix the regulator firmly.
