Variable Attenuator

Variable Attenuator

EFprovide two kinds of variable attenuators for different application. The circular variable attenuator can make theoptical density linearly varies around a 0°-270°circle for measuring laser energe farthest.As for the square one, the optical density linearly varies across the length for measuring laser energe.
