Transmissive Spatial Light Modulator

Our transmissive hexagonal array SLMs are designed for adaptive optics applications. The two dimensional array of Liquid Crystal Variable Retarders acts as a real time programmable phase mask for wavefront correction of a linear polarized source.
Unwanted aberration effects are removed by introducing the opposite phase shift through the Hex SLM. The most common applications involve high-resolution imaging where viewing through an aberrant medium is unavoidable. Examples include astronomical imaging with ground-based telescopes and medical imaging through body fluids. High-energy laser users also benefit from active phase compensation for beam profile correction.
