Method for vacuum deposit on a curved substrate

The invention concerns a method which consists in a process known per se in producing, on the curved substrate ( 10 ) to be treated, a film of material derived from a specific material source ( 13 ). The invention is characterized in that it consists in inserting, between the curved substrate ( 10 )...

Beschreibung
Zusammenfassung:	The invention concerns a method which consists in a process known per se in producing, on the curved substrate ( 10 ) to be treated, a film of material derived from a specific material source ( 13 ). The invention is characterized in that it consists in inserting, between the curved substrate ( 10 ) and the material source ( 13 ), a mask ( 19 ) relative to the curved substrate ( 10 ), preferably selecting as mask ( 19 ), a mask comprising a ring-shaped part ( 20 ). The invention is particularly useful for providing lenses with antiglare treatment.
