Beamsplitter Penta Prism

Beamsplitter Penta Prism is produced by bringing together a precision Penta Prism and a wedge prism and adding an appropriate interference coating to one of the typically reflective surfaces.

Since minor motions of a Penta Prism do not influence the true right angle at which light rays are reflected, the difference between the light rays transmitted and reflected is highly controllable
