Roof Prism

Roof Prism

A roof prism is a transparent optical prism that comprises a segment where two faces meet at an angle of 90 °. The two faces of 90 ° resemble the roof of a house, giving this prism its name. The reflection of the two 90 ° faces returns an image which is flipped laterally around the axis where the faces meet.
