Dispersion prisms, on the other hand, are strictly made for dispersing light and therefore are not suitable for applications requiring quality images. In general, reflective, displacement, and rotation prisms are common in imaging applications. Prisms are classified by shape and/or function. The most common types based on function are dispersion, reflective, rotation, and displacement prisms. However, in addition to their geometrical shape, they are also classified based on their function. ![]() Main TypesĪ prism is typically classified by the shapes of its base, such as triangular, rectangular, and hexagonal. This explains why Newton was able to separate white light into its component colors in his experiments. Different colors of light will refract differently and will also leave the prism at different angles. The refractive index, a dimensionless number that describes how light propagates through that media, typically varies based on the color of light used. Furthermore, it explains the relationship between the angles of the entering and exiting light paths through media with varying refractive indices. Snell’s law, also known as the law of refraction, describes the interaction between light and an optical surface. This change of speed causes light refraction, causing the light to enter the next medium at a different angle. Light changes speed as it moves from one medium to another, such as from air into glass. Isaac Newton’s findings are explained by Snell’s law, which explains the relationship between light and an optical surface. In some cases, a prism has more than one function. The shape of a prism and the angles between its surfaces vary depending on the application. They are made from many types of materials, including glass, plastic and fluorite, and are usually transparent to the region of the electromagnetic spectrum in question. PrinciplesĪ prism is an optical component that disperses or modifies the direction of light. This includes flipping an image over its horizontal or vertical axis, rotating it 180 degrees or even changing the orientation. It also has the ability to inverse, reverse, rotate and orient images. Today, the prism is a powerful tool that offers much more than just dispersing light. Our modern understanding of light and color stems from experiments done in 1672 by Isaac Newton, where he demonstrated the ability of a prism to break up white light into its component colors as well as recombine the spectrum back into white light. In the late 1660s, people believed that color was a mixture of lightness and darkness, and that prisms colored light due to corruption within the glass. Introduction to PrismsĮven as early as in the 13th century, six-sided crystals of natural quartz were used to generate rainbows. ![]() Prisms come in many different shapes and sizes and are used to redirect light through a several different methods. ![]()
