NON POLARIZING BEAM SPLITTER（NPBS）
Basic Parameters
NON-POLARIZING BEAM SPLITTER (NPBS) is made of glass material, through the beamsplitting membrane of the beamsplitting medium to achieve the effect of depolarization, NPBS spectral ratio and the polarization state of the incident light is independent, can make the incident light of any polarization state into two beams of light output close to 1:1, the polarization state of the outgoing light is approximately the same as the incident light.
The mixed film of the boardband depolarization splitting prism has a certain absorption of light energy, but it is very insensitive to the polarization state. It is also insensitive to changes in the Angle of incidence. Considering the metal absorption characteristics in the mixed film layer, it is recommended not to use in the strong laser environment.

POLARIZING BEAM SPLITTER（PBS）
The polarization splitter prism is plated with a multilayer film structure on the inclined surface of the right Angle prism, and then glued into a cube structure. By taking advantage of the property that the transmission rate of P-polarized light is 1 and that of S-polarized light is less than 1 when the light incident at Brewster Angle, the P polarization component can be completely penetrated after the light passes through the multilayer film structure at Brewster Angle for many times. And most of the S polarization component is reflected. Note: Specific bands and extinction ratios can be customized according to customer requirements.
