    • a method and to an apparatus for producing optical glass elements, in particular for producing what is referred to as low-cost optics for focusing light onto small areas, for example, for photovoltaic applications or optical couplers. The method for producing the optical glass elements includes: providing a glass rod having a selected cross-section, heating the glass rod such that it can be deformed in at least some sections, molding at least one optical glass element from the deformable section using a molding tool, separating the optical glass element from the glass rod at the connection, arranging a plurality of separated optical glass elements to form a group, and grinding and/or polishing at least one section of the separating surfaces of the grouped optical glass elements. The invention makes it possible to produce optical glass elements that meet low quality requirements in high quantities and with high output at low cost.

    • The invention relates to a method for ceramizing starting glass of glass-ceramics into glass-ceramics, comprising at least the following steps: 1.1 the starting glass is heated from an initial temperature T1 to a temperature T2 which is disposed above the glass transformation temperature TG at which crystallization nuclei are precipitated; 1.2 the glass is held at the temperature T2 for a period t2 for the precipitation of crystallization nuclei; 1.3 the glass is further heated to a temperature T3 at which a crystal phase grows on the nuclei formed following step 1.1 and 1.2; 1.4 the glass is held for period t3 at a temperature T3 or heated during this period to a higher temperature T4 until the predetermined properties of the glass-ceramics have been reached; 1.5 the control of the temperature curve is performed with the help of a control loop comprising at least one temperature sensor for sensing the temperature and a heating unit as an actuator. The invention is characterized in that 1.6 the heating unit comprises IR radiators for heating the glass to be relaxed with a thermal dead time of less than 10 secs., especially
