optical beamsplitter cube/beamsplitter plate

Beamsplitter Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse 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 absorption loss to the coating is minimal and transmission and reflection approach 50%.
