Liquid Crystal Operating Principles

Liquid Crystal Resources /

Meadowlark Optics DOWNLOAD PRINCIPLES Liquid Crystal Variable Retarders are solid state, real-time, continuously tunable waveplates. Nematic liquid crystals are birefringent materials whose effective birefringence can be changed by varying an applied voltage. Meadowlark Optics Liquid Crystal Retarders are constructed using precision polished, optically flat fused silica windows spaced a few microns apart. The cavity is […]

Spatial Light Modulator Principles

Spatial Light Modulator Resources /

Download Principles Meadowlark Optics award-winning Spatial Light Modulators (SLMs) provide precision retardance control for spatially varying phase or amplitude requirements. Our SLMs consist of liquid crystal (LC) pixels, each independently addressed, acting as separate variable retarders. These SLMs are easily incorporated into optical systems requiring programmable masks and variable input/output devices. Applications include correlation, spectroscopy,
