Wollaston Polarizing Beam Separators (CWPP)
- Bi-refringent polarizers, High polarization purity
- Angular separation of s and p components
- Wavelength range = 350-2300nm
These polarizers provide both s and p polarized beams emerging at an angle from each other. For Wollaston prisms both beams are equally separated from the straight through direction. These Wollaston separators are cemented calcite prisms. Angular separation of the beams is between 15° and 20°.
