Title: Minoru Takada: Innovator in Optical Element Manufacturing

Introduction

Minoru Takada is a distinguished inventor based in Osaka, Japan. He has made significant contributions to the field of optical element manufacturing, holding three patents that showcase his innovative approaches.

Latest Patents

One of his latest patents is a method for manufacturing an optical element of refractive index distribution type. This invention provides a technique for producing a graded refractive index optical element. The method allows for the easy formation of a graded refractive index distribution in a desired portion of a glass substrate without requiring a specific treatment atmosphere or the use of molten salt. Specifically, it involves applying a paste containing a copper compound, an organic resin, and an organic solvent to a glass substrate that contains an alkali metal component. Heat treatment is then performed at a temperature below the softening temperature of the glass substrate.

Another notable patent is a process for producing an optical device. This method enables the production of an optical element without the need for high vacuum, unlike traditional thin film deposition methods, and also avoids the use of molten salt. The process includes applying a paste containing various compounds, such as lithium, potassium, rubidium, cesium, silver, and thallium, along with an organic resin and solvent to a glass substrate. Heat treatment is again conducted at a temperature below the softening point of the glass substrate.
