Right Angle Prisms

Right-angle prisms are typically used to redirect a laser beam or reflect incoming light. By means of total internal reflection, a right-angle prism may be used as a 90° reflector or as a 180° retro-reflector. Right Angle Prisms are Prisms designed with a 90° angle. Right Angle Prisms produce inverted or reverted left handed images, depending on the orientation of the prism. Using two Right Angle Prisms together is ideal for image or beam displacement applications. These prisms are also known as image reflection or reflecting prisms.

XF Photonics provides a wide range of Right Angle Prisms in a variety of sizes, substrates, or reflection or anti-reflection coating options. Aluminum reflection coatings are available for the Prism’s hypotenuse to increase reflectivity. Anti-reflection coatings, including UV-VIS, MgF2, VIS 0°, VIS-NIR, or NIR I, are available for the Prism’s faces to decrease reflectivity in the Ultraviolet (UV), Visible, or Infrared (IR). Laser line anti-reflection coatings are also available for popular laser wavelengths. Substrate options include N-BK7, UV Fused Silica, N-SF11, Calcium Fluoride (CaF2), Germanium (Ge), or Zinc Selenide (ZnSe).
