Overview: 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. Due to total internal reflection (TIR), when the input light is
incident on one of the prism's legs, it undergoes TIR at the
glass/air boundary of the hypotenuse and exits via the other prism
leg. This shows how the right-angle prism can be used as a 90°
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. It
undergoes TIR a second time at the next prism leg and exits the
hypotenuse in a path parallel to that of the input beam. This shows
how the right-angle prism can be used as a 180° retroreflector.
