Title: Eiji Okuda: Innovator in Optical Technology
Introduction
Eiji Okuda is a prominent inventor based in Sakura, Japan. He has made significant contributions to the field of optical technology, particularly in the development of advanced lens systems. With a total of 6 patents to his name, Okuda's work has had a lasting impact on the industry.
Latest Patents
Among his latest patents, Okuda has developed a process for producing a magnetic disk substrate. Additionally, he has created a method for making a plate microlens. This innovative plate microlens features gradient index lenses that have an optical axis aligned with the normal to the surface of a transparent base. The refractive index profile of these lenses gradually changes along the optical axis and perpendicularly. The ratio d/a, where d represents the thickness of the gradient index lens and 2a is the diameter of the lens, falls within the range of 0.46 to 0.78. Furthermore, his method for manufacturing the plate microlens involves forming gradient index lenses with a concentration gradient of a substance to increase the refractive index of the transparent base. This is achieved by using a diffusion preventive mask with predetermined apertures on the surface of the base, allowing the substance to diffuse through the apertures. The ratio a/rm, where rm is the radius of the apertures and a is the radius of the gradient index lenses, satisfies the relation 1.75 ≤ a/rm ≤ 4.5.
