True Zero Order
True Zero Order Waveplate-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.

True Zero Order Single Waveplate
This type of waveplate is made of a very thin quartz waveplate which function as true zeor order. In some cases, the thickness required for single ture zero order waveplates is too thin, they have to be provided as first order waveplate. Specifications:
