-Total internal reflection prism.

-90deg or 180deg beam deflection.

Right angle prisms may be used for beam deviation or as substrates for beam splitters. When a beam enters to one of leg of the prism  normally it arrives at the hypotenuse face with a greater incidence angle than right-angle side. It will go through a total internal inflection at the hypotenuse face and emerges on the other leg face normally. If the beam is inputted normally on the hypotenuse face it will underdog two total internal reflections at the leg faces and emerges in the opposite direction (180deg deflection).
