Description

Non-Polarizing Cube Beamsplitter(NPBS 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. The Beamsplitters coating is able to contain the wavelength from 400nm to 1600nm.It is always used in medical Imaging and test equipment.
