What kind of prism is a dispersion prism? Dispersion prism is one of the types of optical prisms. From a shape perspective, the cross-sectional shape of a dispersion prism is usually a geometric triangle. Although this type of prism is not commonly used in our practical life, it is the most common and commonly used prism in the optical industry, mainly used in the field of light dispersion. Below, we will take a specific overview of dispersion prisms.
Dispersion prisms are mainly used in fields that disperse incident light to its component wavelength. In optics, the cross-sectional shape of dispersion prisms is a geometric triangle, while other shapes of dispersion prisms or those used for dispersion prism groups are also commonly referred to as dispersion prisms. Among them, Dispersive prism is the most widely known optical prism, although it is not common in real life. Dispersion prism is used to disperse light, that is, separate Monochromatic radiation that constitutes polychromatic light. According to the different refraction angles of light with different wavelengths in the same material, the polychromatic light is decomposed into Monochromatic radiation. Dispersive prisms are suitable for decomposing the composition of light, allowing it to present the color of its original spectrum. Because the refractive index is related to the frequency of light, when white light mixed with various frequencies enters the prism, different frequencies are subjected to varying degrees of deflection. Blue light decelerates more than red light, so there is also more deflection than red light. For example, when white light enters the dispersion prism, white light will be scattered to its three components: red, green and blue. The dispersion prism is also suitable for Spectroscopy or laser tuning.
