Abstract
In a device for holding lenses for eye glasses to be coated (,′, . . . ) with a substrate holder (,) consisting of cap-like sheet-metal blanks (,) forming a dish in the form of a spherical segment and having several drill-holes (,′, . . . ), rotating on a vertical axis (R) in the vacuum chamber (,) above a coating source (Q), the coating source (Q) being mounted to the side of the axis of rotation (R) and the lenses (,′, . . . ) being placed and held in the drill-holes (,′, . . . ), the mean perpendicular (M) of the respective drill-hole longitudinal axis (A) intersects the axis of rotation (R) of the substrate holder (,) at a point (O) roughly halfway between the two locations which are the points of intersection (C,F) of the mean perpendiculars (M′,M″) of two notional drill-holes of the same drill-hole pitch circle (T) with the axis of rotation (R), whose drill-hole longitudinal axes (A′,A″) intersect the coating source (Q), the one notional drill-hole however having the largest and the other notional drill-hole having the shortest distance from the coating source (Q).
