Zero Order Waveplate

 

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performance than multiple order waveplates. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications.。

1. Zero Order Waveplates-Optically Contacted

This type of zero order waveplate is constructed of two low order waveplate with their axes crossed. Thus,the effect of the first plate is canceled by the second,except for the residual difference between them.

  • Optically Contacted 
  • AR Coated, R<0.2%
  • High Damage Threshold 
  • Better Temperature Band width
  • Wide Wavelength Bandwidth
