Broadband Non-Polarizing Cube Beamsplitters are made up of a pair of high precision right angle prisms cemented together by a metallic dielectric coating on one of the prisms’ hypotenuse. Because of the metallic dielectric hybrid coating’s low polarization dependence, the transmission and reflection of S- and P-polarization states can be within 10% of each other.
These beamsplitters are spectrally flat across their specified wavelength ranges, which reduces the effects of changes in angle of incidence or converging/diverging beams. Metallic dielectric hybrid coating has <10% absorption, so don’t use it in high power laser.
