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 WebThe name "flint glass" was given to the glassware that was perfected in the late 1670s. It contained a powdered flint that was added to the glass compound during the making process. The flint made the glass both heavy and clearer. At a later date in American history, lead was added to the glass.
