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. FiberPorts can be used to provide a stable platform for coupling light into and out of FC/PC, FC/APC, or SMA terminated fiber with five or six directional adjustments. In essence, a simple collimation lens is all that is needed for this purpose. The working wavelength of the fiber collimator covers 405-1550 nm, and all fiber collimators are. LightPath® Fiber Optic Collimators are designed to collimate light exiting a fiber to a desired beam diameter or spot size or to focus light into a fiber when used in reverse. Naturally, devices for larger collimated beams need to be both longer and larger in diameter.
