Title: Innovations by Stephan Rogels: Patenting a Process for Coating Transparent Substrates
Introduction: Stephan Rogels is an inventive mind based in Rodenbach, Germany, known for his contributions to the field of coating technologies. With a focused expertise in developing processes for transparent materials, he has secured a patent that showcases his innovation and technical acumen.
Latest Patents: Rogels holds a patent titled "Process for coating substrates made of a transparent material." This invention specifically addresses the coating of transparent substrates, such as float glass, with a dielectric layer that has a low refractive index of less than 1.7. The innovative approach utilizes reactive direct current cathode sputtering at a high layer growth rate exceeding 6.0 A cm²/W sec. The process involves a vacuum chamber equipped with a cathode on which a silicide material—preferably nickel disilicide (NiSi2)—is sputtered onto the substrate. The resulting layer on the substrate is a corresponding oxide, such as NiSi-oxide, produced by introducing oxygen as a reactive gas, alongside a noble gas as the process gas.
Career Highlights: Rogels is associated with Leybold Aktiengesellschaft, a company renowned for its advanced vacuum technology solutions. His expertise and innovative mindset contribute significantly to the company's mission of providing state-of-the-art products and services in the coating and vacuum technology sectors.
Collaborations: Throughout his career, Rogels has collaborated with skilled professionals, including Joachim Szczyrbowski and Anton Dietrich. These collaborations have fostered an environment of creativity and innovation, enabling the development of efficient processes and technologies.
Conclusion: Stephan Rogels exemplifies ingenuity in the field of coatings for transparent substrates. His patented process not only enhances the efficiency of producing dielectric layers but also positions him as a noteworthy inventor in his domain. Through his work at Leybold Aktiengesellschaft and partnerships with fellow professionals, Rogels continues to contribute to advancements in technology and innovation.
