Right-Angle Prism

A Right-Angle Prism is used as a mirror to deviate light through 90 degree, and also as a retroreflector to deflect light throgh 180 degree by total internal reflection.

90 degree deflection occurs at the hyotenuse face.The image is erected and reversed.

180 degree deflection uses with hypotenuse as the entrance and exit face.The mail application of it is used as a retroreflector provided that the plane of incident beam includes the vertex.
