Abstract
In apparatus in which an optical device is coated with superposed layers of refractive material by evaporation, a monitor plate is provided on which the layers are coated, means being provided to displace the monitor plate so as to expose a different portion of its surface during the coating of each successive layer. The entire subject-matter of this Specification is contained in Specification 731,865, which is referred to, as also is Specification 731,909.
