Etalons, beam splitter cubes, Faraday isolators, retroreflectors, collimators, and lenses with volume Bragg gratings belong to the group of special optics. These optical components are used in special laser applications.
Beam Splitter Cubes
Beam splitters are used to split a beam into two parts; they can be of differing intensities if necessary.
In general, there are polarization dependent and non-polarizing beam splitters.
In the following, you will find an overview of different beam splitter cubes.
Standard beam splitter cubes are designed for exactly one wavelength and are available with polarization dependent reflection rates from 10 % to 90 %. For this reason, in addition to the desired degree of reflection, the polarization of the beam to be split must be specified.
The cubes are cemented. They can therefore be used for lasers with up to medium power levels.
Non-polarizing beam splitter cubes are designed for exactly one wavelength and do not have any effect on the polarization of the beam to be split. These cubes are available exclusively with a degree of reflection and transmission of 50 %.
Broadband beam splitter cubes are suited for an unpolarized wavelength range. They are designed for a degree of reflection and transmission of 50 %.
