Abstract

Die Erfindung bezieht sich auf ein Verfahren zum Bearbeiten und Berechnen einer als Halbfertigfabrikat ausgebildeten optischen Linse 1 mit einer vorgefertigten Form einer ersten Seite 1.1 und einer zu bearbeitenden zweiten Seite 1.2, bei dem eine Soll-Form einer Oberfläche der zu bearbeitenden zweiten Seite 1.2 berechnet wird, wobei vor der Berechnung der Soll-Form der Oberfläche der zweiten Seite 1.2 eine Ist-Form der Oberfläche der ersten Seite 1.1 durch Messmittel 2 erfasst wird, die Ist-Form der Oberfläche der ersten Seite 1.1 in die Berechnung der Soll-Form der Oberfläche der zweien Seite 1.2 einfließt und das Halbfertigfabrikat mit der Oberfläche der ersten Seite 1.1 mit einem Blockstück verbunden wird, wobei die Ist-Form der Oberfläche der ersten Seite 1.1 nach dem Aufblocken erfasst wird.

The invention relates to a method for processing and calculating an optical lens 1 formed as a semi-finished product with a prefabricated form of a first side 1.1 and a second side 1.2 to be machined, in which a desired shape of a surface of the second side 1.2 to be machined is calculated wherein, before the calculation of the target shape of the surface of the second side 1.2 an actual shape of the surface of the first side 1.1 is detected by measuring means 2, the actual shape of the surface of the first page 1.1 in the calculation of the desired shape of the surface the two side 1.2 flows and the semi-finished product is connected to the surface of the first page 1.1 with a block piece, wherein the actual shape of the surface of the first page 1.1 is detected after blocking.
