摘要: A method of molding an optical element numerically analyzes the thermal stress produced on a molded optical element product within a mold in a visco-elastic temperature range or elastic temperature range of an optical element material in a cooling step of the molding process is on the basis of a visco-elastic characteristic of the optical element material. A correction for the molding face of the mold is made on the basis of the value obtained by the numerical analysis so that any error between the optical functional face of optical element molded by the mold at room temperature and the optical functional face set on design may fall within a tolerance, thereby determining the molding face adapted to the shape of the optical functional face set on design.

摘要: A manufacturing method for an optical glass element having a refractive index equal to a design value after press-molding. A glass material of specified composition is melted and press-molded while it is in the molten state. The refractive index of the glass material is calculated by substracting a change in the refractive index of the glass material resulting from the press-molding from a required refractive index for a molded glass element.

摘要: Lens surfaces are transferred by press-molding a glass material (16) by an upper mold (1) and a lower mold (2). After the lens surfaces are transferred, the outer circumferential portions of the upper and lower molds (1, 2) are clamped and pressed sideways to correct a shift between the optical axes of the transfer molding surfaces of the upper and lower molds (1, 2) and an inclination of the optical axes.

摘要: There is disclosed a method for molding an optical element, by preparing an upper mold member and a lower mold member for press molding a glass material, heating the mold members together or individually to a predetermined temperature, deforming the glass material according to molding faces of the mold members by a pressing force applied to the mold members, then transferring the mold members and the molded glass to a cooling step and subsequently taking out the molded glass by opening the mold members, thereby transferring the optically functional faces corresponding to the molding faces of the mold members, to the glass material. The cooling step includes a step of opening the mold members to separate the glass material from the molding faces of the mold members to release the adhesion state upon press molding between the molding faces and the glass material, and a step of closing the mold members again so as to maintain the molded state of the glass material and cooling the molded glass in this state further to a taking-out temperature thereof.
