The right-angle prism has a basic 45-degree right triangle geometry and is one of the most commonly used prisms for redirecting light and rotating images. It 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.

Product Knowledge
A right-angle prism is used as a mirror to deviate light through 90° and also as a retroreflector to deflect light through 180° by total internal reflection.
