## Description

A right angle prism is an optical prism designed to deviate light by 90° or 180°, depending on the orientation of the prism and the face through which light enters. The joining edges and faces are perpendicular to the base faces, and all joining faces are rectangular.

## Features

- Right angle prisms (RAP) are widely used for rotating image and redirecting the input light.
- High-precision Right-Angle Prisms can be used to deviate a light path by 90° or 180°, depending on which surface is used as the input for the light source.
- The right-angle prism can also be used as a 180° retro reflector. When the input light is incident on the face of the hypotenuse, it undergoes TIR at the glass/air boundary at the prism legs.
- Right angle prism is a glass block in a shape of 45-degree right triangle which operates as reflector and is commonly used as replacement for mirrors to deflect the light beam.
- A right-angled prism is to be made by selecting a proper material and the angles A and B (B?A), as shown in the figure. It is desired that a ray of light incident on the face AB emerges parallel to the incident direction after two internal reflections.
