Since the refractive index of glass may differ with wavelength, just about every property of a lens that relies on its refractive index also varies with wavelength, such as the focal length, the picture distance, and also the impression magnification. The modify of impression length with wavelength is called chromatic aberration, as well as variation of magnification with wavelength is recognized as chromatic variation of magnification, or lateral colour. Chromatic aberration may be eradicated by combining a solid lens of minimal-dispersion glass (crown) with a weaker lens made from higher-dispersion (flint) glass.
