Abstract: A folded camera that includes two light folding elements such as prisms and an independent lens system, located between the two prisms, which includes an aperture stop and a lens stack. The lens system may be moved on one or more axes independently of the prisms to provide autofocus and/or optical image stabilization for the camera. The shapes, materials, and arrangements of the refractive lens elements in the lens stack may be selected to capture high resolution, high quality images while providing a sufficiently long back focal length to accommodate the second prism.

Abstract: Compact folded lens systems are described that may be used in small form factor cameras. Lens systems are described that may include three lens elements with refractive power, with a light folding element such as a prism, located between a first lens element on the object side of the lens system and a second lens element, that redirects the light refracted from the first lens element from a first axis onto a second axis on which the other lens elements and a photosensor are arranged. The lens systems may include an aperture stop located behind the front vertex of the lens system, for example at the first lens element, and an optional infrared filter, for example located between the last lens element and a photosensor.

Abstract: Compact lens systems are described that may be used in small form factor cameras. The lens system may include six 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 system may, for example, provide a focal ratio of 2.1 or less (e.g., 1.8), with full field of view within a range of 70 to 90 degrees (e.g., 81 degrees). The lens system may conform to a criterion for compactness TTL/ImageH

Abstract: A folded lens system that includes lenses with refractive power and two light folding elements such as prisms. A first lens on a first axis refracts light to a first folding element. The first folding element redirects the light from the first axis onto a second axis on which one or more lenses are arranged. The lenses on the second axis refract the light to a second folding element. The second folding element redirects the light onto a third axis on which a sensor is disposed. The lens system may include a front aperture. The sensor may be moved on the third axis to provide autofocusing, or alternatively the lens system may include one or more optical actuators that provide autofocusing. The lens system may have a low F-number (

Abstract: A compact, wide angle, low F-number lens system that may be used in small form factor cameras is described. The compact lens system has six lens elements, and provides high brightness with a low F-number and a wide field of view (FOV) in small form factor cameras. The shapes, materials, and arrangements of the lens elements in the lens system may be selected to correct aberrations, enabling the camera to capture high resolution, bright, high quality images at low F-numbers with a wide FOV. In addition, the shapes and arrangements of the lens elements in the lens system may reduce or eliminate a flare phenomenon.
