Liquid Crystal Controllers

Analog Liquid Crystal Controller (B1010)

The B1010 is an analog Liquid Crystal Controller designed
to integrate with any single (standard) Meadowlark Optics LC device currently offered.

Independent voltage settings allow easy and repeatable
selection of two retardance values. Often, it is desirable to modulate between the two states. For example, switching between quarter‐wave and three quarter‐wave retardance changes linearly polarized light between left and
right circular. A manual toggle allows easy switching between two states. Banana jacks between the knobs allow for continuous voltage monitoring without interfering with LC device connections.

Liquid Crystal Digital Interface Controller (D5020)

The D5020 Liquid Crystal Digital Interface is the next generation in the evolution of Meadowlark Optics Liquid Crystal Controllers. The Digital Controller is designed for user functionality and productivity. The D5020 provides a “set and go” function that
allows the controller to run autonomously without a computer.

Controlling multiple Liquid Crystal cells has never been easier. CellDRIVE 5000 software provides a separate sync output for each channel as well as temperature sensing and control on both channels. The 2 kHz square wave output can be amplitude modulated with sinusoidal, square, triangle, sawtooth
and transient nematic effect waveforms.

Ferroelectric Liquid Crystal Controller (FCS01)

The FCS010 is a two‐channel liquid crystal controller specifically designed to drive our ferroelectric liquid crystal shutters and rotators. It has two short‐circuit protected output channels driven 180 degrees out of phase.

The pre‐configured controller waveforms are optimized for FLC devices. We can tailor the waveform to your specific needs based on application and purchased FLC device. The drive waveform is output through SMA connectors.
