Zero-order waveplate

08 Nov 2019

Zero Order Waveplates,a quarter-or half-wave retarder made from two plates of quartz with 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 dance over a broad range of wavelengths and are more durable than single-element retarders. 

 

Cemented zero-order waveplate is constructed of two multi-order waveplates with their axis crossed. Thus, it performs as a zero-order waveplate because of the effect of two plates counteracting each other. It has wide temperature bandwidth and wavelength bandwidth properties. Because it is cemented, the damage threshold must be considered (about 10MW/cm2) when used. 

 

Key features:

  - Double Plates

  - Broad Spectral Bandwidth

  - Wide Temperature Bandwidth

  - AR Coated
