Abstract
The invention relates to a method for separating a cast lens from shell molds, whereby a separating tool exerts pressure on the lens but a height of the separating tool is guided along the interface between the lens and the shell mold to be separated from the lens. In a preferred embodiment the composite consisting of the lens and the shell molds is fixed on a holding device that can be rotated on an axis of rotation. The holding device is rotated by means of a first motor and the height of the separating tool is tracked by means of a second motor in relation to the height of the interface depending on the angle of rotation.
