Product Description
Optical Prism
An optical prism, a transparent object surrounded by two intersecting but not parallel planes, used to divide or disperse light beams and to adjust the direction of an image. It is widely used in optical instruments, such as spectral instruments, periscopes, binoculars and other instruments. Prisms can be subdivided into the following types according to their properties and uses: right Angle prisms, Pentagon prisms, Dowell prisms, rhombic prisms, ridge prisms, Powell prisms, depolarization splitting prisms and so on.
Pentagon prism
The pentagonal prism is one of beam Angle (90°) steering devices. It serves two purposes:
1. Regardless of the incidence Angle on the first side, the outgoing light turns the incident light to a certain Angle (90°);
2. It differs from a right-angle prism in that the resulting image has neither rotation nor specular reflection. Pentaprisms are commonly used in camera viewfinders, image-viewing systems, or measuring instruments.
