Liquid Crystal-Based Optical Shutter "FOS Series"

Control light transmittance with applied voltage! Vibration-free light shutter series.

The "FOS (Fast Optical Shutter) Series" is a series of liquid crystal-based optical shutters that control light transmittance through an externally applied drive voltage. Compared to conventional mechanical shutters, liquid crystal shutters have no moving parts, which eliminates operational vibrations and allows for a smaller installation footprint. The structure consists of liquid crystal cells sandwiched between crossed linear polarizers, enabling control of light transmittance and functioning as a shutter. By modulating the applied voltage, it is possible to achieve an analog gradation between fully open and fully closed states, allowing it to be used as a variable filter. 【Features】 ■ Low power consumption ■ No moving parts = no vibrations ■ High design flexibility, capable of miniaturization and enlargement ■ High contrast, fast switching ■ Excellent optical quality *For more details, please refer to the PDF document or feel free to contact us.
