Bunryu Arashi is a prominent inventor based in Tokyo, Japan, renowned for his contributions to optical technology. With a total of five patents to his name, Arashi has made significant advancements in the field of microscopy, specifically in the development of immersion microscope objectives.

Latest Patents

Among his latest innovations are two notable immersion microscope objectives. The first patent features an immersion microscope objective that includes a first lens group composed of a first cemented lens, which consists of a planoconvex lens alongside a first meniscus lens. This design includes technical specifications such as a thickness that exceeds the radius of curvature of the lens surface on the image side of the first meniscus lens. The lens configuration satisfies the relationship 2 ≤ h1/h2 ≤ 4, where h1 represents the axial marginal ray height at the lens surface closest to an object, and h2 signifies the height at the lens surface nearest to an image.

The second immersion microscope objective also highlights a precise arrangement, where the first lens group contains a meniscus lens component closest to the image, characterized by a convex surface oriented toward the object. This inventive objective meets conditional expressions that define specific parameters needed for optimal optical performance, including 1.4 < 1.51 and a diameter range of 1.30 mm ≤ (2) ≤ 65 mm.
