摘要： A method for press-forming a glass preform includes the steps of applying positioning pressure to an upper mold as the temperature of the upper mold and a lower mold increase to set values, maintaining a first temperature difference between the upper and lower molds of at least 10.degree. C. and increasing the temperature of the glass preform to a value above its glass transition temperature. Additional steps include cooling the upper and lower molds at a rate of 30.degree. to 100.degree. C. per minute while maintaining a temperature difference between the upper and lower molds at at least the first temperature difference, applying pressure to the lower mold, and opening the upper and lower molds to release the formed optical element after the temperatures of the upper and lower molds decrease to below a set value and a temperature difference between the upper and lower molds becomes greater than the first temperature difference.

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： A method of manufacturing an optical element from glass material is accommodated between an upper member and a lower member of mold. The glass material is press-molded in a state and heated to a desired temperature, thereafter being cooled and released from the mold to form a product having a predetermined optical functional surface. When the product is released from the mold, the upper mold member is first lifted by a predetermined amount, where the product may adhere to the upper mold member. Upon or after releasing and falling of the molded product from the upper mold member due to its own weight or heat stress, the upper mold member is further caused to ascend and the mold is opened so that the molded product can be taken out.
