Latest Patents

One of his latest patents is the Iris Recognition Lens System. This innovative system includes a first lens and a second lens arranged along an optical axis to capture images of the iris and pupil. The design features a reflecting area in the central portion of the first lens and a transmitting area in its circumferential portion. Additionally, the rear part of the first lens has a concave transmitting area and a reflecting area, which enhances the overall functionality of the lens system. The second lens is strategically placed to optimize the imaging process, incorporating multiple reflecting and transmitting areas to reduce the lens length while increasing the focal length.

Another notable patent is the Laminated Lens, which is a high-definition imaging lens assembly designed to minimize the optical path length. This assembly consists of four lenses arranged sequentially along the optical axis. The first lens possesses positive refractive power, while the second lens has negative refractive power. Both lenses are crafted from optical glass, featuring spherical front and rear surfaces. The third and fourth lenses, made of plastic, are spaced apart, with at least one surface of each being aspherical, contributing to the lens assembly's efficiency.
