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 polatization dependence of the metallic-dielectric coating allows the transmission and reflection for S-and P-polarization states to be within 5% of each other.
