Zero-order Waveplate

Zero order waveplate features better performances than multiple order waveplate, as zero order waveplate has lower sensitivity to temperature/wavelength changes.


There are different types of zero order waveplates: compound zero-order waveplate and single plate true zero order waveplate. Compound Zero-Order Waveplates are made from two multiple-order plates with slightly different thicknesses, either cemented, optically contacted or air-spaced. 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.

Features of Zero-order Waveplate

- Low temperature sensitivity
- Wide spectral bandwidth
- High damage threshold (Air-spaced)
- Large sizes available
