Wollaston and Rochon Quartz Prisms

The prisms are produced from high-grade material free of striae and bubbles. The usable spectral range is 0.23 -2.8 µm. The two prism halves are optically contacted. Flatness of the outer faces is λ/10 for λ = 550 nm and deformation of a transmitted plane wave is less than λ/5. The extinction ratio of both beams is 10^-5.
The polarization direction of both beams polarized perpendicular to each other is parallel and vertical to the refracting edge. The cross-section is square; in larger prisms it is octagonal.
See remark for a note on the orientations of Rochon prisms used as polarizers and analyzers.
