    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: An optical imaging lens includes a first lens element, a second lens, a third lens element and a fourth lens element from an object side to an image side in order along an optical axis. An optical axis region of the object-side surface of the first lens element is convex, and an optical axis region of the image-side surface of the third lens element is concave. The lens elements included by the optical imaging lens are only the four lens elements described above. Tavg is an average of four thicknesses from the first lens element to the fourth lens element along the optical axis, an Abbe number of the first lens element is υ1, and an Abbe number of the second lens element is υ2 so that the optical imaging lens satisfies: Tavg≤300 μm, and |υ1−υ2|≤30.000.

    Abstract: An optical lens assembly includes: a first element group including: a first lens group with positive refractive power, including one or two lenses; a second element group including: a second lens group with positive refractive power, including two or three lenses; an optical element including, in order from a visual side to an image source side: an absorptive polarizer, a reflective polarizer and a first phase retarder; and a partial-reflective-partial-transmissive element; and a third element group including an image source plane. The first element group, the second element group and the third element group are arranged in order from the visual side to the image source side. When the optical lens assembly satisfies a specific condition, the weight of the device can be reduced, the zoom function can be provided, and the image quality can be ensured.

    Abstract: A folded telephoto lens system may include multiple lenses with refractive power and a light path folding element. Light entering the camera through lens(es) on a first path is refracted to the folding element, which changes direction of the light on to a second path with lens(es) that refract the light to form an image plane at a photosensor. At least one of the object side and image side surfaces of at least one of the lens elements may be aspheric. Total track length (TTL) of the lens system may be 14.0 mm or less. The lens system may be configured so that the telephoto ratio (TTL/f) is less than or equal to 1.0. Materials, radii of curvature, shapes, sizes, spacing, and aspheric coefficients of the optical elements may be selected to achieve quality optical performance and high image resolution in a small form factor camera.
