Fresnel Rhomb Retarders

Material: BK7 glass or UV grade fused silica.
Based on the principle that total internal reflection
  produces a phase retardation between p- and s-
  components. The retardation is insensitive to wavelength.
Designed to give a retardation of λ/4 or λ/2 over an
  extremely broad wavelength range.
