full-wave plate
A wave plate that introduces a full wavelength (~550 nm) phase difference between the orthogonal polarization components (eigenpolarizations), resulting in non-birefringent materials having a red color.
Synonyms: first order compensator, first order red compensator, first order retardation plate, full wave retardation plate, sensitive tint plate
