Five-axis fiber optic coupler and accessories AFP5-F15P-B

The LBTEK achromatic lens five-axis fiber coupler/collimator with a focal length of 15.0 mm offers three coating options (A/B/C), covering wavelengths from 400-1700 nm. While keeping the connector and fiber stationary, the built-in lens provides five degrees of freedom for alignment: linear alignment in X and Y directions, pitch and yaw angular alignment, and Z-axis adjustment using both pitch and yaw. The achromatic lens has a travel range of ±0.7 mm in 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. Compared to five-axis fiber collimators with aspheric lenses, the achromatic lens version provides smaller focal shift, with detailed comparison curves available on the specifications page. Once the focal length of the achromatic lens five-axis fiber collimator is adjusted, it can generally be used for all wavelengths within the specified band. However, compared to aspheric lenses, it exhibits greater spherical aberration.
