Active Liquid Crystal Device Voltage Controllers — Model LCVRC-2K25

Dual-mode voltage controller for LBTek liquid crystal variable retarders: 2000 Hz AC square wave with ±25 V adjustable amplitude and 0.5-150 Hz modulation frequency.

Overview

The LBTEK Active Liquid Crystal Device Voltage Controller conveniently generates AC square waves with a fixed frequency of 2000 Hz and an adjustable voltage amplitude range of 0-25 V. It also supports dual-voltage output mode, with an adjustable switching frequency between 0.5-150 Hz.

Key Features

  • AC square wave with frequency up to 2000 Hz available
  • Adjustable voltage amplitude range of 0-25 V
  • Dual voltage output mode available with modulation frequency selectable from 0.5 to 150 Hz
  • Panel control, external input control or command-line interface control available
  • Features real-time DC offset monitoring and correction function

Applications

  • Drives LBTek liquid crystal variable retarders (QLCVR / LCVR series) for polarization modulation and adjustable retardance control.
  • Laboratory AC square-wave signal source for liquid crystal device testing.
