Polarizing Beam Splitter Cubes

Cube polarizers for easy alignment. As Glan Taylor / Glan Laser polarizers for extremely high extinction ratios.

With beam splitter cubes, single wavelengths or small wavelength ranges can be split extremely efficiently at a very reasonable price. In general, two different types of polarization optics are used: Polarisation as a result of a coating and as a result of birefringency.

Coating-based Polarizing 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.


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

Polarizing Prisms made from Birefringent Materials

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.



  • Glan-Taylor-Prisma / Glan Laser Prism: Air space design is suited for high power levels
  • Glan-Thompson-Prism: Cemented version; only suitable for low power levels
  • Wollaston Prism: Cemented version; only suitable for low power levels
  • Rochon Prisma: Cemented version; only suitable for low power levels
  • Rhomb-Prism, Beam Displacer

Substrate Materials
