True Zero Order Waveplate
Description
The thickness of a true zero order quartz plate is very thin, it is very easily damaged. In order to solve this problem, we 
can cement the thin quartz plate on a BK7 substrate to increase the strength.

Broad Spectral Bandwidth
Better Temperature Bandwidth
Wide Angle Bandwidth
Cemented True Zero-Order Waveplate is Epoxy Cemented ; Standard Thickness: 1.1±0.2mm
Single Plate True Zero-Order waveplate thickness down to 0.028mm
True Zero Order Waveplates- Single Plate

This type of zero order waveplate is designed for high damage threshold applocation (more than 1GW/cm2). As the 
plate is very thin, its easy to break during operation.
