Device for manufacturing a mould for use in the manufacture of an optical element comprising optical sub-elements mutually arranged in a pattern

An optical element is manufactured by means of a mould by a replication technique including a mold that is manufactured from a ductile metal and is given a mold shape which corresponds to a pattern of sub-elements by means of a die having a die surface which corresponds to the optical sub-element an...

Beschreibung
Zusammenfassung:	An optical element is manufactured by means of a mould by a replication technique including a mold that is manufactured from a ductile metal and is given a mold shape which corresponds to a pattern of sub-elements by means of a die having a die surface which corresponds to the optical sub-element and which is imprinted in the mold with a predetermined force in consecutive positions in accordance with the pattern. A workpiece holder fastened to the mold including a stepped chamber which is displaceable relative to the workpiece holder by a positioning device. The die surface imprints the sub-shape in the mold with a predetermined force substantially independent of a position occupied by the die during imprinting. The predetermined force plastically deforms the ductile metal exclusively at the area of the surface contact between the mold and the die.
