The LBTEK three-axis fiber collimator offers three coating options (A/B/C), covering wavelengths from 350-1700 nm. It is available in three focal lengths: 4 mm, 7.5 mm, and 11 mm. While the connector and fiber remain stationary, the built-in lens provides three degrees of freedom for alignment: pitch and yaw angle adjustment, as well as Z-axis tuning. The pitch and yaw angle adjustment range is ±5°, and the Z-axis travel range is ±1 mm. After inserting the fiber, tighten the side set screw to secure the fiber position. Once alignment is complete, tighten the locking screw on the housing side to fix the Z-axis position. The collimator purchase includes corresponding eccentric adjustment accessories.
