F-O Collimator, FC, 780 nm, 3.0 mm beam

The F-C5-F3-780 Collimator is designed to accept FC type fiber connectors and collimate a 780 nm beam exiting a single-mode fiber to a 3.0 mm beam. Conversely, a laser beam can be launched into the assembly to focus the beam into a connected fiber. High quality, broadband AR coated, glass aspheric lenses are used for low insertion loss and beam sizes only limited by diffraction.

Optical Post Mounting

For post mounting these F-C5 Series collimators, we suggest the model CLH-11 adaptor which fits into most 1 inch mirror mounts.

Applications

Applications include laser beam delivery systems, as well as coupling the output of a fiber into a detector. Applications of pairs of collimators include beam expansion systems for lab applications, as well as fiber-to-fiber coupling in compact components.
