Title: Innovations of James S. Orr
Introduction
James S. Orr is a notable inventor based in Falkirk, GB. He has made significant contributions to the field of optical coatings, particularly focusing on germanium components. With a total of 2 patents to his name, Orr's work has advanced the technology used in optical components.
Latest Patents
Orr's latest patents involve innovative methods for applying coatings to optical components. These components, especially germanium ones, are treated within a vacuum chamber through the production of a glow discharge plasma. This plasma contains carbon and another depositable element sourced from feedstock gases. The gases are introduced into the chamber via mass-glow rate controllers, ensuring a consistent flow rate during specific time intervals. This process results in a multilayer coating with predetermined characteristics. Typically, the coating consists of at least one layer of amorphous hydrogenated germanium carbide, one layer of amorphous hydrogenated germanium, and one layer of amorphous hydrogenated carbon. The arrangement of these layers is such that each second layer is flanked by first layers, while the third layer is bounded on one side by a first layer, with the other side forming the exposed surface of the coating.
