Abstract

The invention relates to a lens-coating gas dispenser and to the corresponding coating device, lens and method. The inventive dispenser consists of a flat outlet plate comprising a plurality of outlet holes which are distributed using the following method consisting in: [a] defining an auxiliary surface; [b] positioning first points on a first flat surface, such that the points are distributed with a constant surface density, said first surface resting on the lower edge of the auxiliary surface; and [c] tracing projection lines from a projection origin, which pass through each of the first points and continue to meet the auxiliary surface, thereby defining projected points on the auxiliary surface, and, finally, tracing downwards from the projected points as far as the flat outlet plate, such as to define the position of the outlet holes.
