Adjustable Focus Laser to Fiber Coupler
Description
The Adjustable Focus Laser to Fiber Coupler is a high-power optical coupling solution designed for applications where coupling efficiency is crucial, especially in high-power situations. It features a special connector that allows precise control of the spacing between the fiber and lens without rotating the fiber.
This is particularly advantageous for polarization maintaining applications, as it maintains the polarization axis. The adjustable focus capability enables compensation for changes in wavelength or beam wave location, optimizing coupling efficiency and minimizing fiber heating.
