The Power and Limitations of Polymers and Liquid Crystals for Polarization Control

Summary Historically, high-quality polarizers like Glan-Thompson types made from calcite have delivered exceptional extinction ratios but come with drawbacks such as small apertures, limited angular fields, and high cost due to the scarcity of optical-grade calcite. Dichroic sheet polarizers are now more common, offering large apertures and wide viewing angles, ideal for displays. However, they […]
