Cemented Zero Order λ/4 Quarter Wave Plate, High Retardance

Overview:

Cemented zero order wave plate is constructed by two quartz plates with their fast axis crossed. The retardance is determined by the difference in thickness between the two quartz plates.

The main difference between cemented zero order waveplates and other kind of waveplates is they have epoxy on its optical path as the two quartz plates are glued with each other by UV epoxy. However, cemented zero order waveplates are superior in the fact they are less sensitive to temperature and wavelength changes comparing to multiple order waveplates.

Main Features of Cemented Zero Order Wave Plate:

Low sensitivity to temperature changes
Broad wavelength bandwidth
AR coated on both surfaces
Available for large sizes
