A dispersion prism is an optical component designed to disperse light into its constituent wavelengths. This dispersion arises from the principle of refraction, where light passing through the prism is bent at different angles depending on its wavelength. When monochromatic light enters a dispersion prism, it is refracted (bent) at each surface, causing different colors (wavelengths) to refract by different amounts due to their shifting wavelengths. This separation of colors results in a spectrum of light emerging from the prism.

Hangzhou Shalom EO offers various kinds of stock and custom dispersion prisms made of BK7, UVFS, and SF11. The dispersion prisms featured on this page are to be used inside the cavity of femtosecond laser, which operates on very low gain laser transitions and even slight reflection losses might be intolerable to it, the dispersion prism serves as a component to reduce reflection loss inside the cavity of the femtosecond laser.
