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.
Precision Optical is pleased to offer right angle prisms and porro prisms in a wide selection of sizes and glass types to meet the requirements of the most demanding applications. Tight surface quality, angles, dimensions, flatness, roof-line quality, and transmitted wavefront are readily available at competitive prices and delivery times. Custom facets, notches and other features are also available. Laser-line and broadband anti-reflection coatings may be applied to the entry faces of the prisms, and protected aluminum, silver or gold coatings are available on the reflecting faces.
