Liquid Crystal Controller Overview
A liquid crystal controller is a device designed to manage the operation of liquid crystal cells by providing the necessary electrical signals to control their optical properties. These controllers are essential for applications requiring precise manipulation of light, such as displays, optical shutters, and variable focus lenses. The controller adjusts the orientation of liquid crystals by applying specific voltages or waveforms, enabling the liquid crystal devices to achieve desired optical states. Advanced liquid crystal controllers often include features like temperature sensing, autonomous operation, and software integration, enhancing their functionality and ease of use in various scientific and industrial applications.
Summary of Models
Model B1010 is an Analog Liquid Crystal Controller compatible with any standard Meadowlark Optics LC device and nematic LC devices meeting specified criteria. It allows for independent voltage settings to select and switch between two retardance values, facilitating modulation between states like quarter-wave and three-quarter-wave retardance. This modulation changes linearly polarized light between left and right circular polarization. The controller features a manual toggle for easy state switching and banana jacks for continuous voltage monitoring without disrupting LC device connections. Each Meadowlark Optics Liquid Crystal Variable Retarder includes a retardance versus voltage plot to ensure precise correlation when used with the Model B1010 Controller.
The D5020 Liquid Crystal Digital Interface simplifies the management of multiple liquid crystal cells with its “set and go” feature for autonomous operation, eliminating the need for a computer.
Key features include:
– CellDRIVE5000 software with separate sync outputs for each channel
– Temperature sensing and control capabilities
– 2 kHz square wave output modulated with various waveforms
The TC3051 from Meadowlark Optics is a microprocessor-based temperature controller designed for Meadowlark Optics’ liquid crystal devices with the Temperature Sensing and Control (TSC) option. It is user-friendly, requiring only plugging, connecting, and powering on.
The FCS010 liquid crystal controller features two output channels tailored for ferroelectric liquid crystal shutters and rotators, such as Achromatic Ferroelectric Liquid Crystal Devices. It offers pre-configured waveforms optimized for FLC devices, which can be customized as needed.
