An optical coating is one or more thin layers of material deposited on an optical component, such as a lens or a mirror. The coating alters the way in which the component reflects and transmits light. Dichroic coatings, also known as long pass/short pass coatings, are designed for application where wavelength separation of incident light in transmission and reflection is necessary. In other words, dichroic coatings are used to selectively pass light of a small range of wavelengths, while reflecting all other wavelengths.
