Cemented True Zero-order Waveplates

The true zero-order waveplate means that thickness of waveplate is very thin (less than 0.1mm) which make the true-zero-order waveplate ecellent in temperature, wavelength and incident angle (about 20º) 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.
