The blocks of optical objects with flat refined faces arranged at exactly controlled angles to each other. These objects can repelled, diverge and turn around the rays of light also dissolve their wavelengths this is known as Prism.
There are several types of prism available each prism contains specific geometry to attain reflections needed to do specific imaging task. Reflecting prisms may overturn, rotate and diverge ray. Dispersing prisms make spectral separation for spectroscopic applications or for change laser output.
Most of the selection of prisms are depends on the application.
It can diverge an incident ray without upturn or reversing to 90 is independent of any revolving of the prism about an axis corresponding to the line of meeting point of the two reflecting countenances. The application of penta prism is it is used in Plumb Level, Surveying, Alignment and Optical Tooling.
Beam splitter Penta Prism:
The application of this prism is used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling.
Right Angle Prism:
Right angle prism is differing or redirects a ray of light with 90 or 180°. The application of this prism is used in telescope, periscope and other optical system.
Dove prism contains two applications.
It is used in terrestrial telescopes, presentation systems and rangefinders.
Corner Cube Retroflector:
It is used to measure the distance, process of optical signal and interferometer laser.
The main application of this prism is it is very easy to revolve elliptical ray into circular ray.
The application of this is wedge prism is to create a few divergence, which don’t permit go back to the basis.
