The cemented true zero order waveplate means that the thickness of waveplate is very thin (less than 0.1mm) which make the true zero order waveplate excellent in temperature, wavelength and incident angle (about 20°) bandwidth. Therefore, it is excellent choice for the highly accurate application. It is cemented with a block of glass which is limited to low and medium power application.
