Cemented True Zero-Order Waveplate                     

The 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 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.

Single Plate True Zero-Order Waveplate             

In order to enable the waveplate suitible for high damage threshold (more than 1GW/cm2) application: Tempotec provides a single plate of true zero-order waveplate. The thickness of this waveplate means handling can be difficult, we can provide mounts upon request.
