Kunshan Nori Optics Introduction: The application of optical prisms

In an optical device, a piece of glass or other transparent material cut at a precise Angle and plane that can be used to analyze and reflect light. Ordinary triangular prisms can separate white light into its constituent colors, called spectra. Every color or wavelength that makes up white light is bent or refracted, but in different amounts. Shorter wavelengths (those toward the purple end of the spectrum) bend the most, while longer wavelengths (those toward the red end of the spectrum) bend the least. This prism is used in certain spectroscopes, in instruments that analyze light, and in determining the identification and structure of materials that emit or absorb light.

Optical prisms refract light to reflect (reflection prism), disperse (dispersion prism) or beam split (beam splitter) light. Prisms are usually made of glass, but other materials can also be used as long as the material is transparent and suitable for the designed wavelength. Common materials include glass, plastic and fluorite.

Optical prisms can reverse the direction of light by internal reflection, so they are widely used in binoculars.

Depending on the application, optical prisms can be made in many different forms and shapes. For example, the Paul prism consists of two prisms that both invert and reverse an image, and is used in many optical viewing instruments, such as periscopes, binoculars, and monoculars.
