Roof Prism |

A Roof prism or Amici Roof Prism is combined with a right angle prism and a totally internally reflecting roof attached to hypotenuse surface. It can invert and reverse an image, also, deflect the image 90° . It is commonly used in terrestrial telescopes, viewing systems and rangefinders.
Roof prism is shaped like a standard right-angled prism with an additional "roof" section (consisting of two faces meeting at a 90° angle) on the longest side. Total internal reflection from the roof section flips the image laterally. The handedness of the image is unchanged.
The roof faces of the prism are sometimes coated to provide mirror surfaces. This allows the prism to be used with a wider range of beam entrance angles without being limited by total internal reflection.
The non-dispersive Amici roof prism should not be confused with the dispersive Amici prism.
