Abstract
Apparatus and method for depositing on the flat surface (4) of a substrate (1) a layer of uniform thickness of particles emitted by a source (5). The substrate (1) is held at the extremity of a radial arm (2) which arm in turn is carried on a rotating axis (3). The substrate also rotates on the arm (2) and is carried on the arm so that the flat surface (4) is orientated such that a line drawn normal to the flat surface forms an angle (.theta.) with the axis (3). The apparatus is particularly suited for the production of optical parts.
