Polarization Beamsplitter Cube (PBS)

03 Mar 2020

The coatings have been designed to hold both the s- and p-polarization components to the same ratio of reflection-to-transmission over a specific laser wavelength region. This means that they will not change the state of polarization of the incident beam .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. All entrance and exit surfaces are coated with a high efficiency, narrowband, anti-reflection coating. We offer both broadband and single wavelength non-polarizing beamsplitters.

Polarization beamsplitter cube split randomly polarized beams into twp orthogonal, linearly, polarized components-S-polarized light is reflected at a 90°. Angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prism cemented together wieh a dielectric coating on the hypotenused of one of prism.
