Abstract
The present disclosure provides an improved production method for optical elements. In this case, it is desirable to achieve high contour accuracy and/or surface quality for optical elements or lenses or headlight lens. In addition, it is desirable to reduce the costs of a production process for objective lenses and/or headlights, microprojectors or vehicle headlights.

1-27. (canceled)
A method of producing an optical element, the method comprising:
- providing a blank of glass;
- providing a first mold;
- providing at least a second mold;
- providing an actuator, the first mold and the actuator being connected by means of a first movable guide rod and at least a second movable guide rod, wherein the first movable guide rod is guided in a first recess in a fixed guide element and the second movable guide rod is guided in a second recess in the fixed guide element;
- heating the blank;
- moving the first mold towards the second mold by means of the actuator;
- and
- press-molding the heated blank between the first mold and the second mold to form an optical element.
A method of producing an optical element, the method comprising:
- providing a blank of glass;
- providing a first mold;
- providing at least a second mold;
- providing an actuator;
- providing a frame, which comprises a first fixed guide rod and at least a second fixed guide rod, wherein the first fixed guide rod and the at least second fixed guide rod are connected at one end by an actuator-side fixed connector and at the other end by a mold-side fixed connector, wherein the at least second mold is fixed to a movable guide element, which comprises a first recess through which the first fixed guide rod is guided and a second recess through which the at least second fixed guide rod is guided;
- heating the blank;
- moving the second mold towards the first mold by means of the actuator in the frame;
- and
- press-molding the heated blank between the first mold and the second mold to form an optical element.
A method of producing an optical element, the method comprising:
- providing a blank of glass;
- providing a first mold;
- providing at least a second mold;
- providing a first actuator, the first mold and the first actuator being connected by means of a first movable guide rod and at least a second movable guide rod, wherein the first movable guide rod is guided in a first fixed recess in a fixed guide element and the second movable guide rod is guided in a second fixed recess in the fixed guide element;
- providing a second actuator;
- providing a frame, which comprises a first fixed guide rod and at least a second fixed guide rod, wherein the first fixed guide rod and the at least second fixed guide rod are connected at one end by an actuator-side fixed connector and at the other end by a mold-side fixed connector, wherein the at least second mold is fixed to a movable guide element, which comprises a first recess through which the first fixed guide rod is guided and a second recess through which the at least second fixed guide rod is guided;
- heating the blank;
- moving the first mold towards the second mold by means of the first actuator;
- moving the at least second mold by means of the second actuator in the frame, and press-molding the heated blank between the first mold and the second mold to form an optical element.
