Latest Patents

Kawamata's latest patents include a process for producing thin films and optical instruments that incorporate these films. The innovative process involves autorotatably installing a substrate in a vacuum chamber. MgF granules serve as the film source material, which are placed in a quartz boat mounted on a magnetron cathode. This cathode is connected to a 13.56 MHz radio frequency power source through a matching box. To maintain a constant temperature, cooling water flows on the lower face of the magnetron cathode. The vacuum chamber is equipped with gas introduction ports for gas entry, and a shutter is positioned between the magnetron cathode and the substrate. This design allows for high-speed sputtering, enabling the formation of thin fluoride films that are free of light absorption.
