Description
Overview
GAOTek laser power attenuator provides 3 kinds of variable attenuators for different applications. The circular variable attenuator can make the optical density linearly vary around a 0° to 270° circle for measuring laser energy farthest. As for square one, the optical density linearly varies across the length for measuring laser energy. Also, the high-power variable attenuator is available for customization.
