  • Patent number: 11347030
    Abstract: Compact lens systems are described that may be used in small form factor cameras. The lens systems may include seven lens elements with refractive power, and may provide low F-numbers with wide field of view while maintaining or improving imaging quality and package size when compared to other compact lens systems. The lens systems may, for example, provide a focal ratio of 1.85 or less, with full field of view of 75 degrees or more. The lens systems may conform to a criterion for compactness TTL/ImageH<1.7, where TTL is the total track length of the lens system, and ImageH is the semi-diagonal image height of the image plane at the photosensor. Lens system parameters and relationships may be selected at least in part to reduce, compensate, or correct for optical aberrations and lens artifacts and effects across the field of view.
