The 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 Solar Valley pentaprism is mature, and it is easy to achieve high-precision dimensions, and the accuracy of the roof pentaprism 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.

Features of Penta Prisms

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.

Penta prisms performance: half 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 °. Penta prisms are commonly used in plumb levels, measurement, calibration, ranging, optical tools, camera viewfinders, and image viewing systems. Solar Valley roof pentaprism in camera achieve optimal performance in ultraviolet (UV), visible or infrared (IR) spectra.
