30° 60° 90° Right Angle Prism

A common application of right angle prisms is as reflectors to change the path of a light beam or to adjust the orientation of an image in optical instruments. Due to the precise angles and reflective properties of right angle prisms, they are often used for accurate deflection of laser beams.A key characteristic of this prism is its high reflectivity, which allows it to reflect most of the incident light in a specific direction with minimal loss of energy. 

30°-60°-90° Right-Angle Prism is a right-angle prism with 30°, 60° and 90° angles, used for beam deviation, dispersion, and critical-angle applications. It can be used as a Littrow dispersion prism when coated.
