Abstract
This invention discloses a machine for automatically attaching an optical filter to a lens. The machine includes lens table for supporting the lens. The machine further includes an attachment-medium dispenser system for dispensing a plurality of gapped-dots of an attachment-medium on a top surface of the lens along a peripheral line substantially according to a bottom-surface shape of the filter. The machine further includes a surface-mounting system for mounting the optical filter onto the top surface of the lens for stamping the gapped-dots into a continuous peripheral attachment-seal for attaching the filter to the lens and for sealing a peripheral interface-edge between the filter and the lens.
Claims24
A machine for automatically attaching an optical filter to a lens comprising:
- a lens table for supporting said lens;
- an attachment-medium dispensing means for dispensing a plurality of gapped-dots of an attachment-medium on a top surface of said lens along a peripheral line substantially according to an interface profile between a bottom-surface of said filter and said top surface of said lens;
- a surface-mounting means for mounting said optical filter onto said top surface of said lens for stamping said gapped-dots into a continuous peripheral attachment-seal for attaching said filter to said lens and for sealing a peripheral interface-edge between said filter and said lens.
A method for automatically attaching an optical filter to a lens comprising:
- providing the lens supported on a table;
- employing an attachment-medium dispensing means for dispensing a plurality of gapped-dots of an attachment-medium on a top surface of said lens along a peripheral line substantially according to an interface profile between a bottom-surface of said filter and said top surface of said lens;
- mounting said optical filter onto said top surface of said lens for stamping said gapped-dots into a continuous peripheral attachment-seal for attaching said filter to said lens and for sealing a peripheral interface-edge between said filter and said lens.
An optical device comprising:
- an optical filter attached to a lens;
- and
- an attachment-medium dispensed on a top surface of said lens along a peripheral line substantially according to a bottom-surface shape of said filter;
- and
- said attachment-medium constituting a continuous peripheral attachment-seal for attaching said filter to said lens and for sealing a peripheral interface-edge between said filter and said lens.
