Fiber Coupling Laser
 

Laser Module with Fiber Coupling

 
All series CNI laser modules can be fiber coupled with different core diameter MM fiber or SM fiber. You have  to refer to the detailed specs of each laser modules (such as power, stability, noise, size, etc) to decide which one is suitable for your application. We would like to do the coupling job for you.

Fiber Collimator

This collimator is designed to connect to the end of FC/PC or SMA905 connector and contains an AR-coated spherical lens. The distance between the spherical lens and the tip of the FC-terminated fiber can be adjusted to compensate for focal length changes, or to re-collimate the beam at the specific wavelength and distance of interest.
 
Adjustable focus optional
 
Customization available
