Crown glass is a type of optical glass used in lenses and other optical components. It has relatively low refractive index (≈1.52) and low dispersion (with Abbe numbers around 60). Crown glass is produced from alkali-lime silicates containing approximately 10% potassium oxide and is one of the earliest low dispersion glasses.

Web1.57-1.75. The index of refraction is the ratio of the speed of light in air to its speed through another media. Flint glass has a relatively high refractive index of roughly 1.66, although some flint glasses are known to have refractive indexes as low as 1.45 and as high as 2.00. Most flint, the mineral, is found in the form of fine-grained ... WebCrown and Flint Glasses. Traditional optical glasses are designated as either crown or flint glasses. Crown glasses were originally based on the soda-lime-silica ternary system and were developed for use as window glass.
