Right-angle prisms are known for the ability to bend the beam or image by 90° or 180°. It is alternative choice for a mirror. Beam deviation depends on which surface beam enters the right-angle prism. The reflection inside the prism is achieved due to total internal reflection at glass and air boundary. These prisms can also be used for wavelength dispersion.
