Optical Prisms
• Plentiful options of substrates from DUV to IR
• Custom design of dimension and shape
• Wide range of types
• Precise processing and coating
• High laser damage threshold
Optical Prisms are widely used to redirect light at a designated angle. They 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.
WISOPTIC offers a wide range of optical prisms with various designs, substrates, or coatings. For example, Penta Prisms, Right Angle Prisms, Dove Prisms, Roof Prisms, Porro Prisms, Retro-Reflectors, Anamorphic Prism Pairs, Pellin Broca Prisms, Equilateral Dispersive Prisms etc. Substrates options include BK7, UVFS or SF11 optical material. AR coating options include MgF2, UV-VIS, UV-AR, etc.
