摘要： In an eccentricity measuring method according to the present invention, a first position of a light source image formed by reflection at one optical surface is measured (S2), a predetermined second position related to another optical surface is measured (S3), and a relative eccentricity between both optical surfaces is calculated based on the first and second positions (S5). Therefore, the eccentricity measuring method enables measurement of eccentricity by a same measurement optical system regardless of a radius of curvature of an optical surface of an optical element.

摘要： There is provided a method of manufacturing a molded glass body, wherein, in a mold-releasing step of releasing and withdrawing a molded body obtained after pressure-molding, from molds, relative positions of an upper mold and a lower mold are moved to take a retracting position at which, even if the molded glass body which has stuck on the upper mold falls down from the upper mold, the molded glass body does not fall on the lower mold. Thus, even if the molded body falls down from the upper mold, the molded glass body does not damage the lower mold.
