Flint glass is optical glass that has relatively high refractive index and low Abbe number (high dispersion). Flint glasses are arbitrarily defined as having an Abbe number of 50 to 55 or less. The currently known flint glasses have refractive indices ranging between 1.45 and 2.00. A concave lens of flint glass is commonly combined with a convex lens of crown glass to produce an achromatic doublet le… 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.
WebMay 14, 2024 · Flint glass is produced using lead, while crown glass contains a higher level of potassium oxide. Mechanical Properties. Optical glass is valued for its transparency, purity, and hardness compared to other types of glass. Optical glass is manufactured to be particularly dense, with a density up to 6.19 g/cm³. Flint glass tends to be denser ... WebCrown glasses have low refractive indices and low to moderate dispersions. The first flint glasses were potash-lead-silicate glasses prepared using English ‘flint’ as the source of silica. The presence of lead in these glasses results in higher refractive indices and dispersions than those of crown glasses.
