LENS HOLDER, ESPECIALLY HOLDER FOR EYE GLASS LENSES TO BE COATED IN A HIGH VACUUM VACUUM DEVICE OR SPUTTER

摘要

In a lens mounting, especially for spectacle glass lenses (25) to be coated in an apparatus for high-vacuum evaporation or for sputtering, which is essentially constructed as a ring (15), which supports the lens (25) to be held and, for its part, can be connected to a substrate mounting (4) which is held in the process chamber of the high-vacuum apparatus in the vicinity of the coating source, the lens (25) can be inserted between two rings (14, 15) which can be clamped against one another via wire springs (16, 17), the first ring (14) being provided on its outer circumferential surface (22) with ramps (30, 31) which co-operate with the wire springs (16, 17), which are attached to the radially outer circumferential surface (23) of the second ring (15), at least one of the rings (14) having at its radially outer circumferential surface (22) two diametrically opposite pins (18, 19) with which it is supported in corresponding bearing forks (20, 21) of the substrate mounting (4) and in which it can be rotated by approximately 180 DEG . …IMAGE…
