Cemented Zero Order λ/2 Half Wave Plate, High Retardance Overview: Cemented zero order wave plate 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 waveplate features better
performance than multiple order waveplate, as zero order waveplate
has lower sensitivity to temperature and wavelength changes. Main Features of Cemented Zero Order Wave Plate: - Low sensitivity to temperature changes
- Wide wavelength bandwidth
- Both sides AR coated
- Large sizes available
