Multiple retaining device for substrates to be treated, for example to be cleaned and then to be coated by vacuum deposition or cathode sputtering

摘要

The multiple retaining device for substrates to be treated, preferably for ready-ground spectacle glass lenses which are to be cleaned and then to be coated, has four bars (1a-1d) arranged like a system of coordinates, in which the sides of the bars facing the four quadrants have grooves for receiving the substrates (11) to be treated which are pressed against the grooves by springs (4a-4d). Main use for secure retention and transferring of substrates for a plurality of successive process steps. <IMAGE>
