Chromatic aberration can be minimized by using an achromatic lens. This type of lens is usually composed of two individual lenses made from glasses with different amounts of dispersion. The use of a strong positive lens made from a low dispersion glass like crown glass coupled with a weaker high dispersion glass like flint glass can correct the chromatic aberration for two colors, | Chromatic aberration can be minimized by using an achromatic lens.

The use of a strong positive lens made from a low dispersion glass like crown glass coupled with a weaker high dispersion glass like flint glass can correct the chromatic aberration for two colors, for example red and blue.<ref> http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/aber2.html</ref> | ||
