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.
A right angle prism mirror is usually used to turn a light path or deflect an image produced by an optical system by 90°.Depending on the orientation of the prism, the image can be aligned left and right, upside down and left and right.Rectangular prism can also be used for image combination, beam deviation and other applications.
When a right angle optical prism is used, some optical film is usually plated.The rectangular prism itself has a large contact area and such typical angles as 45° and 90°. Therefore, compared with ordinary reflectors, the rectangular prism is easier to install and has better stability and strength for mechanical stress.They are the best choice of optical parts for all kinds of devices and instruments.
