Cube polarisers allow for easy alignment. In contrast to TFP polarisation beam splitters, the beam does not incur an offset in beam splitter cubes.
With beam splitter cubes, single wavelengths or small wavelength ranges can be split extremely efficiently at a very reasonable price.
Polarizing beam splitting cubes are mainly used because of their easy alignment feature. The cube polarisers 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.
