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

The zero order waveplates or retarders are 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.

Hangzhou Shalom EO offers the custom zero order waveplates or retarders upon customer's request, and the stocked modules are also available in fast delivery and low cost.
