Optical Cone Prism
Cone prism consists of three mutually perpendicular surfaces and a string of right-angle surface integral. Its shape is equivalent to the cube of optical glass by a ridge at an angle to cut down the tetrahedron. If the three right-angle surface are accurate 90 °, the incident light by the string side in turn reflected by the three right-angle surface even after the original direction of outgoing light path. As the cone prism characteristics, not only in military, aerospace use, but also widely used in the distance mapping,
