Five-axis fiber optic coupler and accessories FP5-F7AP-A

The LBTEK aspheric lens five-axis fiber coupler/collimator with a focal length of 7.5 mm offers three coating options (A/B/C), covering wavelengths from 350-1700 nm. While the connector and fiber remain stationary, the built-in lens provides five degrees of freedom for alignment: linear alignment in the X and Y directions, pitch and yaw angular alignment, and simultaneous adjustment of the Z-axis using pitch and yaw. The aspheric lens has a travel range of ±0.7 mm in the X and Y directions, with a resolution of 317 µm per revolution. The Z-direction travel range is ±1.0 mm, with a resolution of 200 µm per revolution. Additionally, loosening the three flat-head screws on the front panel allows rotation of the connector for polarization-maintaining fiber alignment. After alignment, tighten the locking screws on the side of the housing to secure the X and Y positions. The lock ring on the Zθ adjuster can fix the pitch/yaw position. Five-axis fiber couplers with FC/PC interfaces and an effective focal length ≤7.5 mm can be used with both FC/PC and FC/APC connectors, as the combination of five-axis adjustment and short focal length makes off-axis output negligible.
