Consisting by triangular blocks of glass with two 45° and one 90° angles, right angle prism is common used to bend image path or redirect light. From the different position of prisms, the image will invert or revert through the right angle(90°). Right angle prisms is typically used in image or beams displacement applications. 

Hangzhou Shalom EO offers right angle prisms made of N-BK7, UV Fused Silica, N-SF11, Calcium Fluoride (CaF2), Germanium (Ge), or Zinc Selenide (ZnSe). Prism's hypotenuse to could bee Aluminum reflection coated to increase reflectivity, and Anti-reflection coatings are available for the Prism's faces to decrease reflectivity in the Ultraviolet, Visible, or Infrared. Laser line anti-reflection coatings are also available for popular laser wavelengths.
