Off axis parabolic mirrors have a wide range of applications in terahertz and infrared bands, and off axis mirrors are one of the commonly used components for building terahertz and infrared optical paths. The off axis high anti parabolic mirror is based on the principle of a geometric paraboloid, which can focus parallel incident collimated beams/collimated THz waves onto the focal point, and can also convert terahertz or infrared waves emitted by a point light source into parallel transmitted beams.
