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. Its performance is as good as cemented zero-order waveplate. Additionally the air-spaced construction enables it is suitable for the high power laser application. The damage threshold is more than 500MW/cm2. |
