Definition: Adjective: referring to lens elements of optical system with many layers of lens coating (of transparent dielectric material) to increase transmission of light and reduce reflection: layers are usually arranged with alternately low and high refractive index. * Multi-coating can ensure optics transmit nearly 100% of incident light and help ensure a neutral colour image by compensating for colour of glass or pass specific wave-bands of light.
