Variable Attenuator
 

Variable  Attenuator

 
CNI provide two 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.
