Difference between crown and flint prism

The difference between crown and flint glass is how much they disperse or spread out the colors. Crown glasses have relatively low dispersion, while flint glasses have relatively high dispersions. It is the difference in dispersion that allows a crown and a flint to be combined to make an achromat. Glasses with big differences in dispersion work best, allowing relatively shallow curves and good control of aberrations.
