Title: The Innovative Contributions of Atsushi Ohata
Introduction
Atsushi Ohata is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technology, holding a total of 11 patents. His work primarily focuses on lens systems and imaging apparatuses, showcasing his expertise in optical design and engineering.
Latest Patents
Ohata's latest patents include a lens system and an imaging apparatus designed for moving objects. The lens system features a positive first lens group, an aperture diaphragm, a positive second lens group, and a third lens group, arranged sequentially from the subject side. This innovative design includes at least three positive lenses and one negative lens in the first group, while the second group comprises four or more lenses, including at least one cemented lens. Additionally, a negative lens with a concave surface is positioned toward the subject side. The third lens group contains three or more lenses, including both positive and negative lenses. This configuration allows for smooth focusing from infinity to short distances, with specific movements of the lens groups to maintain image clarity.
Another notable patent is a zoom lens that consists of a first lens group with negative refractive power, a second lens group with positive refractive power, and a third lens group also with positive refractive power. As the zoom lens transitions from a wide-angle to a telephoto setting, the spacing between the first and second lens groups is reduced, while the spacing between the second and third groups changes. This design incorporates multiple lenses with varying refractive powers, ensuring high-quality imaging across different focal lengths.
