Zero order waveplates feature better performances than multiple order waveplates as they have broader bandwidth and lower sensitivity to temperature or wavelength changes.
Features of Zero Order Waveplates
- Low Temperature Sensitivity
- Wide Spectral Bandwidth
- High Damage Threshold (Air Spaced)
- Large Sizes Available
There are different types of zero order waveplates: single plate true zero order waveplate and compound zero-order waveplate. Compound Zero-Order Waveplates are made from two multiple-order plates with slightly different thicknesses, which are cemented, optically contacted or air-spaced for application with higher laser power. The slow axis of one waveplate is aligned with the fast axis of the other waveplate. The difference in thickness is selected to obtain the required net phase change. Such zero order waveplate can work in a broad wavelength range with low temperature sensitivity.
Slow Axis
OptoCity offer all types of zero-order waveplates either in stock or custom made. Please specify the type if you have specific need.
