Title: Joseph Charles Crifasi: Innovator in Optical Mirror Substrates
Introduction
Joseph Charles Crifasi is a notable inventor based in Stoddard, NH (US). He has made significant contributions to the field of optical technologies, particularly through his innovative methods for coating metallic substrates. With a total of 2 patents to his name, Crifasi continues to push the boundaries of optical performance.
Latest Patents
Crifasi's latest patents focus on enhanced performance metallic-based optical mirror substrates. The method he developed involves diamond turning a substrate to achieve a surface roughness between about 60 nm and 100 nm RMS. This substrate can be made from either metal or metal alloy. Following the diamond turning process, the surface is polished to a roughness of between about 10 nm and 25 nm to create a polished substrate. The process also includes heating the polished substrate and ion bombarding it with an inert gas. Finally, a coating comprising at least one metallic layer is deposited on the ion bombarded surface using low-pressure magnetron sputtering. The coating is then polished to achieve a finished surface with a roughness of less than about 25 nm RMS using a glycol-based colloidal solution.
