Latest Patents

Hiroshi Ushida holds a patent for a variable focal distance lens system and imaging device. This invention features a first lens unit and a third lens unit that are rotationally symmetrical with respect to an optical axis. The design includes a first freeform-curved surface lens and a second freeform-curved surface lens, which are identical in shape and positioned to rotate 180 degrees around the optical axis. The refractive power of the second lens unit is adjustable, allowing for movement in opposite directions of the first and second freeform-curved surface lenses. This mechanism enables the lenses to transition from a wide-angle end state to a telephoto end state by moving in the Y-axis direction in conjunction with other lens groups.
