Description
When the connector and the fiber remain stationary, the internal lens has five alignment degrees of freedom: linear alignment in the X and Y directions, pitch and yaw alignment angles, and adjustment of the Z-axis using both pitch and yaw. The travel range in the X and Y directions is ±0.7mm, the travel range in the Z direction is greater than 2 mm, and the pitch and yaw adjustment range is ±4°. It has good structural stability and high coupling efficiency. If the wavelength of the light source is changed, the collimator needs to be re-adjusted to achieve higher coupling efficiency.
