Fiber-optic Collimator, FC, 1550 nm, 2.0 mm beam

The F-C5-F2-1550 Collimator is designed to accept FC type fiber connectors and collimate a 1550 nm beam exiting a single-mode fiber to a 2.0 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. Beam pointing accuracy is better than 1.0°.

FC or SMA Fiber Connections

F-C5 Series collimators accept common FC or SMA type connectorized optical fiber.

Optical Post Mounting

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

Advanced AR Coatings Offer Excellent Performance

High quality, broadband AR coated, glass aspheric lenses are used for low insertion loss and beam sizes only limited by diffraction. Coatings are offered for 543 nm, 780 nm, 1310 nm, and 1550 nm.

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.
