Non-polarizing Beamsplitter Cube
1. Overview
Consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic-dielectric coating allows the transmission and reflection for S- and P- polarization states to be within 6% of each other. This means that they will not change the state of polarization of the incident beam.
We offer both broadband and single wavelength non-polarizing cube beamsplitters. An antireflective coating has beem applied to each face of the beamsplitter in order to produce maximum transmission efficiency for the appropriate wavelength range.
To select a suitable beamsplitter, you need to consider the type, coating, transmission range and damage threshold.
