Latest Patents

Hiroto Ishikawa holds a patent for "Optical multilayer thin-film filters and methods for manufacturing same." This patent describes optical multilayer thin-film filters (OMTFFs) that consist of a transparent substrate, a multilayer film (MF) on the substrate's surface, and a top layer. The MF is composed of alternating layers of high-refractive-index (HRI) and low-refractive-index (LRI) materials. The top layer is made from a material with atoms of lower atomic weight than those in the HRI or LRI materials. The manufacturing process occurs in a vacuum environment, where thin films of HRI and LRI materials are alternately laminated onto the substrate. A unique suppression step is included, where the newly formed MF is briefly exposed to moisture, preventing the migration of low-molecular-weight atoms into the HRI and LRI materials. Hiroto Ishikawa has 1 patent to his name.
