Apparatus and method for producing thermally prestressed glass panes and thermally prestressed glass pane

摘要

It is a device (1) and a method for producing thermally prestressed glass panes (7) is specified. By means of a measuring device (4), the optical anisotropy of a glass pane (7) at a plurality of measurement points, by way of the surface of the glass pane (7) are distributed, are measured, so that a heating device (2) during heating and / or a cooling device (3) during cooling of the glass panes (7) on the basis of this measured data for controlling. Furthermore, a thermally prestressed glass pane (7) is specified in the undesirable color effects are reduced.
