Prisms & Rhombs

Produce quarter-wave, half-wave, or other retardations with broadband sources or multiple wavelengths over 8 - 12 µm.

These Fresnel prisms and rhombs use total internal reflection to produce a phase change between s- and p-polarizations that is nearly wavelength independent. This enables straight-through and angled components with virtually any desired retardation.
