Non polarizing Beamsplitter Cube 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 5% 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 (NPBS). An antireflective coating has beem applied to each face of the beamsplitter in order to produce maximum transmission efficiency for the appropriate wavelength range.

What is the use of NPBS?
NPBS is applied in optical systems requiring low polarization dependence. In optical measurements, it maintains the incident light’s polarization to ensure accuracy. In projection systems, it evenly splits beams, enhancing image brightness and color uniformity. In interference experiments, it guarantees consistent polarization of beams, improving interference effects. Its properties make it crucial in scenarios needing precise beam - splitting without altering polarization.
