Latest Patents
Segawa's latest patents include an optical system and imaging device that features a unique configuration of lens groups. The first patent describes an optical system that consists of a first lens group with refractive power and a second lens group with positive refractive power. This design allows for a variable distance that changes during focusing, which is closer to the object than the variable distance between other lenses. The first lens group includes a positive lens and one or more negative lenses, while the second lens group comprises a lens subgroup with positive refractive power, an aperture stop, and another lens subgroup that also has positive refractive power. The second lens subgroup includes both a negative lens and a positive lens, adhering to a predetermined conditional expression.
Another patent by Segawa focuses on an optical system and imaging device that includes two lens groups with alternating refractive powers. Similar to his previous work, this design emphasizes the importance of the variable distance during focusing, enhancing the overall performance of the imaging device.
