Cemented True Zero Order Waveplate
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.
- Standard Thickness: 1.1 ± 0.2 mm
- Epoxy Cemented
- Moderate Damage Threshold
- Better Temperature Bandwidth
- Wide Wavelength Bandwidth
- Good wavefront and parallelism
