Optical right-angle prism 

A wave plate works by shifting the phase of the incident light wave between two perpendicular polarization components. Liansheng optics offers variety of mounted zero order airspaced waveplates of different clear aperture size and designed for different wavelengths. Waveplates of other types and dimensions are also available upon request.

1.Precision phase delay

2. Compound zero-order wave plates offer a lower dependence on temperature,wavelength and incidence angle  than multi-order wave plates .

3. Zero-order wave plates are made from high quality Quartz crystal  By aligning the fast axis of one plate with the  slow axis of the other mutual coincidence,  the difference of thickness is λ/4 or λ/2. 

4  . Other wavelength and size of the wave plate can be customized.
