Ball lens is a short focal length glass ball that can obtain the desired focal length by selecting different material refractive index and spherical curvature. In the field of fiber communication,TO-CAN can be made by using a ball lens and a metal tube shell, which can be combined with a laser (LD) to couple the light into fiber. Ball lens is also used to collimate the divergent beam emitted by lasers into parallel beams or couple parallel beams into a detector (PD).

C-lens is a small cylindrical lens with axial light transmission, which is mainly used inthe fields of optical communication and laser technology. Using a C-lens to make fiber collimator can collimate the divergent light emitted from the fiber into parallel beam and couple parallel beam into the fiber. C-lens is also used to collimate the divergent beam emitted by a laser (LD) or couple the parallel beam into a detector (PD).
