Polarizing Beam Splitter Cubes

Polarizing beam splitting cubes are mainly used because of their easy alignment feature. The cube polarizers are usually cemented and beam splitting occurs at a 90° angle. We offer both narrow band and broadband versions of different quality levels. Special designs were developed for high power laser applications and feature damage thresholds in the J/cm² range.

Types

• Narrawband polarizing beam splitter cubes
• High power polarizing beam splitter cubes
• Broadband polarizing beam splitter cubes

By means of birefringence, unpolarized light is divided into two rays. Polarization of the ordinary beam runs perpendicular to the optical axis, the extraordinary beam, however, oscillates parallel to the optical axis of the crystal.
