WAVEPLATE
Zero Order Waveplates
The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performances than multiple order waveplates, it has brod bandwidth and a lower sensitivity to temperature and wavlenght changes.
Specifications
Material: Quartz
Dimension Tolerance: +0.0, -0.1 mm
Wavefront Distortion: <λ/8 @ 632.8 nm

Note: Other wavelengths within the ranger of 200-2300nm are also available upon request.
Cemented Zero Order Waveplate
This type of zero order waveplate is constructed of two multiple order waveplates with their axes crossed. Thus, the effect of the first plate is canceled by the second, except for the residual difference between them.

True Zero Order Waveplates-Cemented
This type of zero order waveplate is constructed of a true zero order waveplate and a BK7 substrate.As the waveplate is very thin and easy to be damaged,the Bk7 plate's function is to strengthen the waveplate.
