Multiple Order Waveplates λ/2, λ/4
Waveplates are used in the synthesis and analysis of polarized light. Quarter waveplates transform linearly
polarized light into circularly polarized light, and vice-versa. Half waveplates rotate the plane of polarization of
linearly polarized light through any angle. They also convert left circularly polarized light into right circularly
polarized light, and vice-versa. Multiple Order Waveplates are made from a single crystalline quartz plate.
Retardation varies quickly with wavelength, thus they are generally useful only at their design wavelength.
Retardation is also a function of plate thickness and
is slightly temperature dependent due to thermal
expansion.
