Right-angle prisms are commonly used to redirect light paths or deviate images formed by an optical system by 90°. Depending on the orientation of the prism, the resulting image can be inverted top-to-bottom with left-to-right correctness, or reversed left-to-right with top-to-bottom correctness. Right-angle prisms are also utilized for image combining, beam displacement, and other applications. Right-angle prism: Efficiently utilizing critical angle characteristics for total internal reflection of incident light is one of the fundamental functions of a right-angle prism.
