Optical Fiber Coupler, GRIN Lens, Polarization Preserving Fibers

The F-926 GRIN Lens Fiber Coupler provides a convenient means of aligning fibers with GRIN lenses to obtain efficient laser-fiber coupling and output collimation in a compact space. The Model F-926 has the ability to rotate the chuck to align a bare polarization-preserving fiber with an incident laser polarization. Optimal coupling efficiency is achieved with ultra-fine 100-pitch X-Y adjustment screws allowing for precise fiber positioning. Axial Z motion is accomplished without rotation of the fiber by a knurled knob with a precision 80 TPI thread. Two couplers can be used together for efficient fiber-to-fiber coupling. This makes it easy to insert a breadboard or prototype optical system into existing fiber optic equipment. An instruction sheet provides helpful advice on aligning the coupler with an external source or a second coupler. GRIN lenses and bare fiber chucks are sold separately. The couplers mount to Newport tables and breadboards via a single bolt.
