Beamsplitter Cube is a more sophisticated type consisting of two right- angle prismscemented together at their hypotenuse faces.The cemented face of one prism is coated.Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection approach 50%.
