Optical Prisms are used to redirect light at a designated angle. Optical Prisms are ideal for ray deviation, or for adjusting the orientation of an image. An Optical Prism’s design determines how light interacts with it. When light enters an Optical Prism, it either reflects off an individual surface or several surfaces before exiting, or is refracted as it travels through the substrate. For example, when light enters a right angle prism, it reflects off a single surface, causing the light to redirect at 90°. When light enters a wedge prism, though, a change in substrate thickness causes the light to deviate through refraction.

Edmund Optics offers a wide range of Optical Prisms in a variety of designs, substrates, or coating options. Designs include Right Angle, Amici, Penta, Schmidt, Wedge, Anamorphic, Equilateral, Dove, or Rhomboid prisms, in addition to Corner Cube Retroreflectors or Light Pipe Homogenizing Rods. Anti-reflection coatings include MgF2, UV-VIS, UV-AR, VIS 0°, VIS-NIR, or multiple laser-line options.
