Abstract
Abstract A lens holder, particularly for eyeglass lenses to be coated in a high-vacuum vapor deposition or sputtering system, is formed as a ring pair. The ring pair is connectable to a substrate holder that is mounted in the process chamber of the high-vacuum system in the proximity of a coating source. The lens can be placed between the rings of the ring pair, which are secured to one another by resilient wires. An outer surface of a first ring is provided with ramps that interact with resilient wires that are secured to the outer surface of a second ring. One of the rings includes two diametrically opposite pegs which serve to pivotably mount the lens holder in bearing forks mounted on the substrate holder. The lens holder is capable of 180° of rotation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
A lens holder for eyeglass lenses to be coated in a high-vacuum vapor deposition or sputtering system, said holder being connectable to a substrate holder that is held in a process chamber of said high-vacuum system in the proximity of a coating source, said lens holder comprising: a first ring having an outer surface from which extend resilient members; a second ring having an outer surface upon which is provided channel means for selective securing engagement with said resilient members; and means for mounting a lens between said first and second rings; further comprising a pair of pegs mounted diametrically opposite one another on an outside surface of one of said rings; and bearing means on said substrate holder for supporting said lens holder via said pegs.
Claim 2
Dependent Claim
127 words
A lens holder for eyeglass lenses to be coated in a high-vacuum vapor deposition or sputtering system, said holder being connectable to a substrate holder that is held in a process chamber of said high-vacuum system in the proximity of a coating source, said lens holder comprising: a first ring having an outer surface from which extend resilient members; a second ring having an outer surface upon which is provided channel means for selective securing engagement with said resilient members; and means for mounting a lens between said first and second rings; further comprising a pair of pegs mounted diametrically opposite one another on an outside surface of one of said rings; and bearing means on said substrate holder for supporting said lens holder via said pegs.
Claim 3
Dependent Claim
27 words
A lens holder according to claim 1, further wherein said means for mounting said lens comprises a flanged step provided in at least one of said rings.
Claim 4
Dependent Claim
39 words
A lens holder according to claim 1, further wherein said channels means comprises a pair of channels lying diametrically opposite one another and extending longitudinally at approximately a 30° angle relative to a circumferential plane of said second ring.
Claim 5
Dependent Claim
48 words
A lens holder according to claim 1, further wherein said resilient members comprise wire springs, each having a first end secured to an outer surface of said first ring, and a second end bent to form a bight that extends at an angle approximately parallel to said channels.
Claim 6
Dependent Claim
169 words
A lens holder for eyeglass lenses to be coated in a high-vacuum vapor deposition or sputtering system, said holder being connectable to a substrate holder that is held in a process chamber of said high-vacuum system in the proximity of a coating source, said lens holder comprising: a first ring having an outer surface from which extend resilient members; a second ring having an outer surface upon which is provided channel means for selective securing engagement with said resilient members; and means for mounting a lens between said first and second rings; further comprising a pair of pegs mounted diametrically opposite one another on an outside surface of one of said rings; and bearing means on said substrate holder for supporting said lens holder via said pegs; further comprising a finger extending from at least one of said pegs and made from a ferromagnetic material; and magnet means arranged on said substrate holder for selectively retaining said finger, and thus said lens holder, on one of two rotational positions.
Claim 7
Dependent Claim
169 words
A lens holder for eyeglass lenses to be coated in a high-vacuum vapor deposition or sputtering system, said holder being connectable to a substrate holder that is held in a process chamber of said high-vacuum system in the proximity of a coating source, said lens holder comprising: a first ring having an outer surface from which extend resilient members; a second ring having an outer surface upon which is provided channel means for selective securing engagement with said resilient members; and means for mounting a lens between said first and second rings; further comprising a pair of pegs mounted diametrically opposite one another on an outside surface of one of said rings; and bearing means on said substrate holder for supporting said lens holder via said pegs; further comprising a finger extending from at least one of said pegs and made from a ferromagnetic material; and magnet means arranged on said substrate holder for selectively retaining said finger, and thus said lens holder, on one of two rotational positions.
Claim 8
Dependent Claim
130 words
In a high-vacuum vapor deposition or sputtering system including a substrate older, a lens holder comprising: a first ring pivotally attached to said substrate holder by pivot means comprising a finger extending transversely from a rotational axis of said first ring, said first ring being pivotable between first and second rotational positions; a second ring including a step arrangement adapted to receive a lens; at least two channel members mounted substantially diametrically opposite one another on said first ring; at least one resilient member on said second ring, said at least one resilient member being capable of securing engagement with said channel members of said first ring; and retaining means, on said substrate holder, for selectively retaining said finger, and thus said lens holder, in one of said rotational positions.
Claim 9
Dependent Claim
130 words
In a high-vacuum vapor deposition or sputtering system including a substrate older, a lens holder comprising: a first ring pivotally attached to said substrate holder by pivot means comprising a finger extending transversely from a rotational axis of said first ring, said first ring being pivotable between first and second rotational positions; a second ring including a step arrangement adapted to receive a lens; at least two channel members mounted substantially diametrically opposite one another on said first ring; at least one resilient member on said second ring, said at least one resilient member being capable of securing engagement with said channel members of said first ring; and retaining means, on said substrate holder, for selectively retaining said finger, and thus said lens holder, in one of said rotational positions.
