Porro Prism A refracting optical prism used in optical instruments to modify image orientation, In use, the light enters through the largest rectangular plane in the prism, passes through two total reflections of the inclined plane, and then penetrates the original plane of incidence, Because the light comes in and out normally, the prism does not disperse. But the image that passes through Porro prism will be flipped 180 degrees, and it will travel in the direction it entered, which means it will travel 180 degrees.

Prisms Optical Components Right Angle Prism Supplier:ChangChun BRD Optical co., Ltd PARAMETER: Right angle prisms 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 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.
