These fiber couplers are designed to connect the ends of FC/PC, FC/APC or SMA905 connectors. They contain an AR-coated aspheric lens. The distance between the aspheric lens and the tip of the FC-terminated fiber can be adjusted to compensate for focal length changes or to re-collimate the beam at the desired wavelength and distance.

Please do not hesitate to enquire about the compatibility of couplers for your laser needs.
