02 Jun 2021 Right-angle prism mirrors are extremely versatile optical components, commonly used as individual prisms and components of optical assemblies. A beam of light entering the leg of a right-angle prism mirror will deviate by a nominal value of 90°, while precise rotation of the prism controls beam alignment. When light enters the hypotenuse of the prism, it is commonly called a Porro prism. In this configuration, a light beam will undergo 180° deviation that is invariant in the azimuthal axis, while precise adjustment of the prism controls beam elevation. |
