Since the refractive index of glass differs with wavelength, each and every property of the lens that will depend on its refractive index also varies with wavelength, such as the focal size, the graphic distance, plus the graphic magnification. The transform of picture distance with wavelength is known as chromatic aberration, along with the variation of magnification with wavelength is recognized as chromatic variation of magnification, or lateral colour. Chromatic aberration can be eradicated by combining a strong lens of lower-dispersion glass (crown) with a weaker lens made from high-dispersion (flint) glass.
