Latest Patents
One of Nara's latest patents focuses on high magnification compact zoom lenses. This invention is designed to reduce the diameter of lens groups closer to the imaging plane, resulting in downsized and lightweight zoom lenses capable of achieving magnifications as high as 20 diameters. The design incorporates an image stabilizer or vibration compensating mechanism that is also minimized in size. The improved zoom lens consists of four groups of lens pieces arranged in a specific order to optimize performance. The first lens group is of positive refractivity, followed by a negative refractivity group, and two additional positive refractivity groups. This arrangement allows for effective displacement of the lens optics from the wide-angle to the telephoto end while maintaining image quality.
