What is a Multi-Twist Retarder?
Multi-Twist Retarders (MTRs) offer remarkably effective control of broadband polarization transformation. They provide bandwidths and general behavior that matches or exceeds all traditional approaches using multiple homogenous retarders. MTRs form the platform for ImagineOptix SA-QW – the highest performing super achromatic quarter wave plate in the world.
How It Works
MTRs use a self-aligning process on a single substrate to build up multiple layers of LC to create nearly arbitrary bandwidths and shapes. MTRs reduce fabrication cost and complexity, and enables higher precision and almost ideal performance predicted in theory.
