Supports Multimode Fiber Applications
The LBTEK Three-Axis Fiber Optic Collimator offers three coating options (A/B/C) covering wavelengths from 350-1700 nm. It is available in focal lengths of 4 mm, 7.5 mm, and 11 mm. The built-in lens provides three degrees of alignment freedom: pitch and yaw angle adjustment, and Z-axis adjustment, while keeping the connector and fiber stationary. The pitch and yaw angle travel range is ±5°, and the Z-axis travel range is ±1 mm. After inserting the fiber, tightening the side-set screws locks the fiber in place. Once aligned, tightening the locking screws on the housing fixes the Z-axis position. The collimator purchase includes the corresponding eccentric adjustment parts.
