Cemented Zero Order Waveplate
Cemented zero order waveplate is constructed by two quartz plates with their fast axis crossed, the two plates are cemented by UV epoxy. The difference in thickness between the two plates determines the retardance. Zero order waveplates offer a substantially lower dependence on temperature and wavelength change than multi-order waveplates.
- Better Temperature Bandwidth
- Wide Wavelength Bandwidth
- Both Sides AR Coated
