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 energe farthest.
As for the square one, the optical density
linearly varies across the length for measuring
laser energe. |
