Basic Liquid Crystal Controller

Meadowlark Optics’ Basic Liquid Crystal Controller is designed to integrate with any single (standard) Meadowlark Optics Liquid Crystal device presently offered as well as any nematic Liquid Crystal device compatible with the specifications listed. Digital LED voltage and frequency readouts provide added convenience. Frequency and voltage settings can be easily stored by simply pressing the adjustment knob. In addition, system memory retains voltage and frequency settings at power down.
With a Liquid Crystal Variable Retarder, manual adjustment of the voltage amplitude controls the device retardance. Independent voltage settings allow easy and repeatable selection of two retardance values. A manual toggle allows easy switching between two states.
The Basic Liquid Crystal Controller is equipped with internal modulation control. The Internal Frequency knob adjusts periodic switching between the two voltage settings. An external input allows modulation to run synchronously with other equipment.
