   For example, the dichroic prism assembly used in some cameras requires two dielectric coatings, one long-wavelength pass filter reflecting light below 500 nm (to separate the blue component of the light), and one short-pass filter to reflect red light, above 600 nm wavelength. The remaining transmitted light is the green component.

   Longer wavelengths (red) are diffracted more, but refracted less than shorter wavelengths (violet). Main article: Dispersive prism Dispersive prisms are used to break up light into its constituent spectral colors because the refractive index depends on wavelength ; the white light entering the prism is a mixture of different wavelengths, each ...
