Abstract: Lens systems are described that may be used in small form factor cameras. An imaging lens system may include a front aperture and five lens elements, and provides a low F-number ( =82 degrees), and short total track length (TTL). 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.

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 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.

Abstract: An optical component includes a mask defining a light blocking portion and a light transmitting portion of the optical component. The light blocking portion is separated from the light transmitting portion by one or more mask edges, at least one of which is defined by an apodized pattern. The apodized pattern of the mask edge reduces diffraction and thus flare caused by the mask.

Abstract: Compact folded lens systems are described that may be used in small form factor cameras. Lens systems are described that may include five 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: 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: An optical system includes a first light folding element (e.g., a prism), a second light folding element (e.g., another prism or a mirror), and a lens system located between the first light folding element and the second light folding element. In some cases, the lens system includes a lens stack having either four or five lens elements with refractive power. The first light folding element redirects light from an object field from a first axis to the lens system on a second axis. The plurality of refractive lens elements in the lens stack refract the light to the second light folding element. The second light folding element redirects the light from the second axis onto a third axis to form an image of the object field at an image plane. The optical system has a 35 mm equivalent focal length within a range of 85 to 160 mm.
