Air Spaced Zero Order Waveplate

Description

Air spaced zero order waveplate is constructed by two quartz plates installed in a mount, to form a air gap between the two quartz plates. 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.

High Damage Threshold
Better Temperature Bandwidth
Wide Wavelength Bandwidth
AR coated and Mounted
RoHS Compliant
