A Wollaston prism is an optical device that manipulates polarized light. It separates randomly polarized or non-polarized light into two orthogonal linearly polarized outgoing beams.
The Wollaston prism consists of two orthogonal calcite prisms, cemented together on their base to two right triangle prisms with perpendicular optic axes. The Wollaston prism is commonly used as a polarizing beam splitter. The deviation of the two transmitted beams are nearly symmetric about the incident beam direction. The polarization of the output beams are parallel and perpendicular to the plane where the entrance and exit beam lie.
The Wollaston prism is mounted in an anodized housing. A white marking line is engraved on the exit end face of the installed Wollaston prism housing. Light enters from the end with the retaining ring, and after passing through the Wollaston prism, it splits into two beams (o-light and e-light with mutually perpendicular vibration directions).
