Penta prism is a five sided prism. It reflects light rays through a 90oangle by two reflections. It does not invert or revert the image. The reflecting surfaces are aluminized. Slight movement of the prism does not affect the true right angle at which light rays are reflected. This feature makes this prism useful in range-finders. It also shortens the length of an instrument.
