The 50% / 50% visible Cube Beamsplitter consists of two cemented right angle prisms. One prism is coated on the hypotenuse to provide a coating that will reflect and transmit the incident light. The coating shows minimum sensitivity to variations in angles of incident and polarizations as compared to plate beamsplitters. The cube beamsplitter generally enables the optical system to have greater resolution than is possible with a plate type beamsplitter since asymmetrical optical aberrations are eliminated. The Cube Beamsplitter is also available in any split between reflection and transmission on special order.
