<p>The invention provides a small, IVD machine, especially for coating spectacle lenses. The machine has an IVD chamber (104) containing at least two sputtering target materials (134, 136), and a movable shield (140) which covers the or each target except the one which is sputtering and the shield is positionable so that any one of the targets can sputter whilst the other or others is/are closed. The machine has control means so that when the articles are placed in the chamber and the chamber closed, the process can be completed automatically without the chamber being opened in the meantime and the target materials can be sputtered in any programmed sequence and programmed period of time.</p> |
