 Variable Attenuator |
| AZURE 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. |
