Beam splitters are used to split a beam into two parts; they can be of differing intensities if necessary.
In general, there are polarisation 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 polarisation dependent reflection rates from 10 % to 90 %. For this reason, in addition to the desired degree of reflection, the polarisation 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 polarisation 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 %.
