Meadowlark Optics, Inc. Liquid Crystal Variable Retarder LRC-200

Description
To prevent ionic buildup, which can damage the liquid crystal layer, liquid crystal devices should be electrically driven with an AC waveform with little to no DC component. We require a 2 kHz square wave of adjustable amplitude for controlling our Liquid Crystal Variable Retarders (LCVRs). Our Basic Controller and Four Channel Interface ensure these drive requirements are met. A temperature sensing and control option can be added to our LCVRs for accurate control of the operating temperature. A temperature sensor is attached directly to the LCVR substrate, outside its clear aperture and a heater is attached to the LCVR housing. This provides active heating and passive cooling of the liquid crystal device.
