Right-angle prism is the most common type of prism. It is used to re-direct a beam of light at 90 degrees from the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.
Corner Cube Retro-Reflectors have three mutually perpendicular surfaces and a hypotenuse face. It operates on the principle of total internal reflection (TIR). A beam entering the effective aperture is reflected by the three roof surfaces and emerges from the entrance/exit surface parallel to itself. This property is independent of the orientation of the retro-reflector, within ac......
Penta prism can deviate an incident beam without inverting or reversing to 90 degree. The deviation angle of 90 degree is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, ......
Invented by H.W. Dove, Dove Prisms have also known Reversion prisms. When the prism is rotated about its length axis, the image viewed through the prism rotates at twice the prism rotation rate. This is an unusual and sometimes useful property for special applications. Entry and exit faces are anti-reflection coated. ......
Roof prism is combined with a right-angle prism and a totally internally reflecting roof attached to the hypotenuse surface. It can invert and reverse an image, also, deflect the image 90?. Therefore, it is often used in terrestrial telescopes, viewing systems and rangefinders. ......
Rhomboid prisms are commonly used to displace a laser beam without changing its direction. In imaging applications, rhomboid prisms will displace the optical axis without inverting the image. COE Optics can manufacture different sizes of Rhomboid prisms by sapphire, fused silica, BK7 etc. material which is from UV, visible and NIR ran......
