The UV Continously Variable Attenuator Module (UV C-VARM) contains two wedge attenuators that are continuously variable and a step attenuator that allows attenuation from 10⁷:1 down to 3000:1. The C-VARM can be finely adjusted to achieve both precise attenuation levels and maximum use of the camera's optical dynamic range. Optical filter elements have have 1/10th wave flatness specifications to minimize wavefront distortion when multiple elements are employed in the beam path.

Key Features:

• UV-enhanced laser-grade attenuation optics
• Compatible with all Coherent beam diagnostics cameras
• Virtually undistorted and interference-free attenuation
• C-Mount threads couple directly to cameras

This module incorporate male C-mount connection flanges and has been designed for use with LaserCam-HR II Camera Profilers.
