Method and apparatus for producing optical element |
摘要 |
A method and an apparatus for producing an optical element, e.g. of glass or plastic, capable of performing a molding temperature control required for a plurality of independent molding blocks (11) in a short period of time, and continuously and simultaneously producing a plurality of different optical elements having a high degree of accuracy at a low cost by press-molding is provided. The temperature control (27) acts on heaters (7) provided in upper and lower plates (27) of each heating and cooking section (3-6). The plates (27) exchange heat with the molding block (11), enclosing the material to be molded (17), by contact. The plates (27) are provided with means (8), such as a WC-based coating, on the surface which contacts the molding block (11) for rendering temperature uniform across the plate mold contact surface. <IMAGE> |
