SMA-Fiber Focuser

The FSM series of fiber focusers employ optimized multi-element design in ruggedized aluminium packages. They are suitable for single mode and multi-mode fibers with FC/PC or SMA905 fiber optic connectors. All lenses are AR-coated for low insertion loss. Every fiber focuser provides a fixed magnification rate and working distance ideal for various laser applications.
