The Liquid Crystal Variable Attenuator from Meadowlark Optics gives users continuous, real-time control of light intensity. The attenuator consists of our Liquid Crystal Variable Retarder, with attached compensator, operating between crossed linear polarizers.

The attenuator can be configured with high-efficiency calcite or beamsplitting polarizers to maximize light transmission and increase the threshold for damage. Key benefits of the Meadowlark Liquid Crystal Variable Attenuator are its continuous control of light intensity, capability to be controlled by computer, and high contrast ratio.
