What is optical prism?

Prism, in optics, a piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colors, called a spectrum.
 

Characteristics of Prisms

Prism's ability to be modeled as a system of plane mirrors in order to simulate the reflection of light within the prism medium. 
Replacing mirror assemblies is perhaps the most useful application of prisms, since they both bend or fold light and change image parity. 
Often, multiple mirrors are needed to achieve results similar to a single prism. 
Therefore, the substitution of one prism in lieu of several mirrors reduces potential alignment errors, increasing accuracy and minimizing the size and complexity of a system.

Types of optical prisms

There are four main types of prisms: dispersion prisms, deviation, or reflection prisms, rotation prisms, and displacement prisms. 
Deviation, displacement, and rotation prisms are common in imaging applications; dispersion prisms are strictly made for dispersing light, therefore not suitable for any application requiring quality images.

Dispersion Prisms

Optical prism dispersion is dependent upon the geometry of the prism and its index dispersion curve, based on the wavelength and index of refraction of the prism substrate. 
The angle of minimum deviation dictates the smallest angle between the incident ray and the transmitted rays. 
The green wavelength of light deviates more than red, and blue more than both red and green; red is commonly defined as 656.3nm, green as 587.6nm, and blue as 486.1nm.

People also ask

• What eye conditions require a prism?
  A prism may fix double vision from eye misalignment when caused by: Eye muscle problems, such as myasthenia gravis, Graves' disease, or strabismus Neurological  issues, such as head injuries, stroke, migraine, or tumor.
   
• Can you read with prism glasses?
  Prism reading glasses are spectacles that turn your vision 90 degrees towards your feet, allowing you to read a book or watch TV while laying flat on your back. They use prisms, not mirrors, to turn your line of sight, removing the reversed image and distortion that is typical of mirrors.
