DEVICE FOR HOLDING LENSES, ESPECIALLY FOR EYE GLASSES TO BE COATED IN A VACUUM COATING OF SPUTTERING MACHINE

摘要

It is being coated (in 3,3 equipment of lens for keeping glasses. A substrate holder (4) by formed in the form of a spherical segment disk and with it is several drilling (5,5 cover shape sheet-metal blank (4a, b, c, d) form in the case where. A vertical axis (R) rotation being wound in the vacuum chamber (2) on a painting source (Q), applies source (Q), is installed in rotary shaft (R) and lens (3,3 side. It is placed and is fixed on drilling (on 5,5. The average vertical (M) of respective drilling longitudinal axis (a) is being substantially rotary shaft (the R) (C for intersecting the substrate holder (4) of (O) on one point between the point of intersection to stop at two positions, F) average vertical (M, M) the drilling of two concepts of the identical drilling pitch circle (T) with rotary shaft (R), its longitudinal axis (a that drills, a) intersect painting source (Q), however there is the drilling of that concept of maximum and another concept drilling, there is the shortest distance from painting source (Q).
