WebOct 31, 2000 · Long-crown and short-flint glass have very high refractive powers, so lenses using this glass will be very sensitive to tolerances. Any theoretically calculated imaging performance – however high it may be – is useless if the calculated quality cannot be reliably achieved due to excessively high sensitivity to tolerances. The author WebFamous for having 10 percent potassium oxide, a compound that makes glass low-refractive in nature, crown glass is an almost obsolete type of glass. It used to be used as window glass during the 16th through 19th centuries. By the early 20th, there were better options. Even so, you might find it in antique furniture and art pieces.

WebA typical “standard glass” achromat is made of a low dispersion crown glass and a high dispersion flint glass. However, whilst an achromatic doublet is a big step forward when compared to a simple lens as it reduces the amount of chromatic aberration over a certain range of wavelengths, they do not produce perfect correction.
