Optical lens with negative focal power and concentric circle structure
The granted patent (Publication Number: US11921265B2) discloses an optical lens comprising a series of lenses with specific characteristics to achieve a maximum field of view (FOVm), overall focal length (F), and image height (Ym) relationship that satisfies a specific formula. The lens system includes a combination of lenses with negative and positive focal powers, concave and convex surfaces, and specific configurations to meet the defined criteria. Additionally, the patent mentions the gluing of certain lenses together to form the optical lens.
Furthermore, the patent includes a detailed description of various configurations and characteristics of the individual lenses within the optical system, such as the focal powers, surface curvatures, and thicknesses. Specific relationships between the focal lengths of different lenses, overall focal length of the system, and total track length of the optical system are outlined to ensure optimal performance. The patent also specifies conditions for achromatic lens groups and provides ranges for various parameters to achieve the desired optical outcomes. Overall, the patent presents a comprehensive design for an optical lens system that meets specific field of view and focal length requirements while incorporating a combination of different lens types and configurations.
