Zero-Order Waveplate
Zero-Order Waveplate
Low-Order Waveplate
Polarizing Rotator
A quarter- or half-wave retarder made from two plates of quartz with their fast axes crossed, the difference in thickness between the two plates determines the retardance. Zero-order retarders provide accurate retardance over a broad range of wavelength and are more durable than single-element retarders.
