Right Angle Prism
Description
A Right-Angle Prism is used as a mirror to deviate light through 90 degree, and also as a retroreflector to deflect light through 180 degree by total internal reflection.
90-degree Deflection
90 degree deflection occurs at the hypotenuse face. The image is erected and reversed.
180-degree Deflection
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.
