Prisms

Right Angle Prisms

Right angle prism can bend the incidence light at 90 degree or 180 degree. For a 90 degree deflection the total internal reflection occurs at the hypotenuse face to invert image and achieve a 90 degree change in direction. For a 180 degree deflection the hypotenuse face is used as the entrance and exit face. It is applied for laser beam bending light deviation image, image erection in periscopes and telescopes, retro-reflectors, and mirrors. Metal housing, standard and broadband antireflection coatings are available upon request, see our standard optics components below.
