Abstract
A device for depositing a high quality thin film of material upon a surface is disclosed. The device is particularly adaptable to the construction of mirrors since it allows for coating of alternating layers of material. The quality of the film deposited is greatly improved by placing the substrates adjacent to the target surface and not directly in front of it. Furthermore, the substrates are rotated to improve uniformity of the coating.
