Zero 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. Zero Order Waveplates
are made from two crystalline quartz plates of similar thickness, that
are optically contacted together with orthogonally aligned optical axes.
Retardation varies slowly with wavelength, thus they are useful with
tunable or broadband sources. Retardation is a function of thickness difference between the two plates, and is
essentially invariant with temperature.
