86-755-82924037The penta prism precisely defines a right Angle and is independent of the Angle of incidence. After two total 270 ° reflections inside the prism, the incoming light is emitted from adjacent surfaces at a precise 90 °. The processing technology of Tianyanggu pentaprism is mature, and it is easy to achieve high-precision dimensions, and the accuracy of the prism with a size of less than 3 inches can be controlled within 2 seconds. After milling, fine grinding, grinding and polishing, the roof prism can achieve high precision mirror flatness and Angle accuracy.

One-stop customized production: Solar Valley optical prism manufacturer processes various sizes of pentaprisms according to customer requirements.
Material: Optical glass, fused quartz 7980, JGS1, JGS2 and other materials are used.
Pentaprism performance: Pentaprism precisely defines a right Angle, and is independent of the Angle of incidence. After two total 270 ° reflections inside the prism, the incoming light is emitted from adjacent surfaces at a precise 90 °. Pentaprisms are commonly used in plumb levels, measurement, calibration, ranging, optical tools, camera viewfinders, and image viewing systems. Tianyanggu Pentaprisms achieve optimal performance in ultraviolet (UV), visible or infrared (IR) spectra.
