Amici roof prism

Non-dispersive prism in astronomy

An Amici roof prism, named for its inventor, the Italian astronomer Giovanni Battista Amici, is a type of reflecting prism used to deviate a beam of light by 90° while simultaneously inverting the image. It is commonly used in the eyepieces of telescopes as an image erecting system. It is sometimes called an Amici prism or right angle roof prism. The non-dispersive Amici roof prism should not be confused with the dispersive Amici prism.
