F-916 In Stock

The F-916 by Newport is a Six-Axis Polarization Maintaining Fiber Coupler engineered to facilitate precise laser beam single-mode coupling into an exposed PM optical fiber. Designed with meticulous attention to detail, this coupler features a rotatable chuck mount, specifically tailored to align polarization-preserving fibers with precision. This coupler's exceptional sub-micron position resolution plays a pivotal role in achieving high-efficiency single-mode coupling. To ensure pinpoint accuracy in directing a focused laser beam onto the fiber end face, the F-916 is equipped with a three-axis positioner that securely holds the fiber chuck. This component is augmented by high-resolution 100 TPI adjustment screws, which guarantee smooth XY adjustments, as well as a knurled knob that facilitates 80 TPI thread axial Z motion. For further refinement in beam alignment, the coupler offers fine-tuning tilt adjustments that introduce a second-order translation of the beam. This coupler also boasts a fixed optical axis height set at a nominal 3 inches and a strategically designed base featuring a pattern of clearance and tapped holes, providing convenient compatibility for mounting on breadboards and tables.
