Description Overview GAOTek circle portable variable attenuator provides 3 kinds of variable attenuators for different application. The circular variable attenuator can make the optical density linearly varies around a 0° to 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.
