Penta Prism is a five-prism with two reflective surfaces at 45 ° perpendicular to each other, and two refractory faces perpendicular to the entry and emerging beams. The regular Penta Prism reflecting surfaces are coated with aluminium or enhanced aluminium. It can be used as a High Precision Beamsplitter Prism by inserting a wedge for deviation correction in output beam surface.
