Zero order waveplate is a quarter or half-wave retarders made from two plates of quartz within their fast axes crossed. The difference in thickness between the two plates determines the retardance. Zero order retarders provide accurate retardance over a broad range of wavelengths and are more durable than single element retarders. Zero order waveplate shows better performance than multiple order waveplates it has broad bandwidth and a lower sensitivity to temperature and wavelength changes. Cemented zero order waveplates are cemented by Eproxy. |
