Made of a transparent substance, such glass or plastic, a prism lens is an optical device with at least one optical surface—typically two—that refracts and/or reflects incident light to separate the constituents of a light wave. Depending on how they are made, prisms can distribute, deflect, reflect, or focus light, among other things.

1.Dispersing prisms: Because different light wavelengths are refracted at different angles as they pass through the prism, these prisms have the ability to separate white light into various hues of the spectrum. Red, orange, yellow, green, blue, indigo, and violet are the seven colors that light can be divided into, for instance, using a triple prism.

2. Prisms Lens : These prisms combine the capabilities of a lens and a prism, and they can be used to concentrate or diverge light as well as alter the direction in which light propagates.

3. Reflecting prisms: These prisms are frequently employed in telescopes, cameras, and other optical instruments to collapse or alter the direction of light streams because of their internal reflection.

4. Polarizing prisms: These prisms are frequently employed in polarized light experiments and in certain kinds of displays because they can separate light from a mixture of light in a specific direction of polarization.

Numerous disciplines, including astronomy, photography, laser technology, optical instruments, and scientific experiments, rely on prisms. To guarantee that the prisms can precisely carry out the intended optical function, considerations like the material’s refractive index, dispersion characteristics, and manufacturing tolerances must be made while designing prisms.
