Abstract
An installation, a carrier, and a method for coating eyeglass lenses are provided, wherein a carrier with eyeglass lenses held in a rotatable manner is conveyed in succession in different coating devices or coating lines, in order to coat in an alternating manner opposite sides of the eyeglass lenses and/or to apply different coatings. In particular, the carriers with the eyeglass lenses are conveyed from a coating device or coating line by an evacuated transfer chamber to another coating device or coating line.
Claims20
Method for coating eyeglass lenses in an installation in a vacuum by means of gaseous-phase deposition, comprising:
- providing the eyeglass lenses first with a first coating or basic coating in a coating device or coating line and then with at least one further coating comprising one or more anti-reflective layers or a mirror coating, in another coating device or coating line, with at least one of the following features:
- the eyeglass lenses are conveyed from the coating device and/or coating line for the first coating or basic coating, subsequently through a transfer chamber under vacuum to the other coating device and/or coating line;
- and/or
- wherein the eyeglass lenses are coated in groups of up to 10 eyeglass lenses in the respective coating device.
Method comprising:
- coating eyeglass lenses in a vacuum, by means of gaseous-phase deposition, wherein a carrier holds multiple eyeglass lenses to be coated,
- wherein the method includes at least one of the following features:
- the carrier is fed in succession to different coating devices where the eyeglass lenses are coated, wherein the coating devices are separated from one another by means of locks during coating,
- and/or wherein the eyeglass lenses are rotated around their own axes during the coating;
- and/or
- the carrier is coupled to a toothed rack or to a carriage or frame for conveying into or through at least one coating device.
