Non-polarizing Beamsplitter Cube

Non-polarizing Beamsplitter Cube


Non-Polarizing Cube Beamsplitters consist of a pair of high precision 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 hybrid coating allows the transmission and reflection of S-polarization and P-polarization states to be within 6% of each other. These beamsplitters are spectrally flat across their specified wavelength ranges, reducing effects caused by changes in the angle of incidence or converging/diverging beams.
