Introduction

Brian C Monachan is a notable inventor based in Glasgow, GB. He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work primarily focuses on the development of advanced optical filters and coatings.

Latest Patents

One of his latest patents involves the creation of optical filters with coatings that are transmissive in narrow waveband regions. This optical filter consists of a multilayer coating that adheres to a substrate, comprising at least four superimposed layer collections. Each layer collection includes ordered first, second, and third layers, with the first and third layers made of a first material that is 0.6 quarter wavelengths thick, while the second layer is made of a second material that is 6.8 quarter wavelengths thick. The high refractive index material used is zinc sulphide, and the low refractive index material is thorium fluoride. This optical filter is generally transmissive except in specific narrow waveband regions that correspond to known laser wavelengths.

Another significant patent by Monachan pertains to optical coatings for components, particularly germanium components. This innovation involves applying a coating on the exposed surface within a vacuum chamber through the production of a glow discharge plasma. The plasma contains carbon and another depositable element from feedstock gases, which are fed into the chamber via mass-glow rate controllers. The coating typically consists of multiple layers, including amorphous hydrogenated germanium carbide, amorphous hydrogenated germanium, and amorphous hydrogenated carbon, arranged in a specific order to achieve desired characteristics.
