Variable Attenuator
 

Variable  Attenuator

 
CNI provides 3 kinds of variable attenuators for different application. The circular variable attenuator can make the optical density linearly varies around a 0°-270° circle for measuring laser energy farthest. As for the square one, the optical density linearly varies across the length for measuring laser energy. Also the high power variable attenuator is available for customization.
