  • Publication number: 20200026033
    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 ration (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.

  • Patent number: 10338344
    Abstract: A compact telephoto lens system that may be used in a small form factor cameras. The lens system may include five lens elements with refractive power. Alternatively, the lens system may include four lens elements with refractive power. At least one of the object side and image side surfaces of at least one of the lens elements is aspheric. Total track length (TTL) of the lens system may be 6.0 mm or less. Focal length f of the lens system may be at or about 7.0 mm (for example, within a range of 6.5-7.5 mm). Lens elements are selected and configured so that the telephoto ratio (TTL/f) satisfies the relation 0.74<TTL/f<1.0. Materials, radii of curvature, shapes, sizes, spacing, and aspheric coefficients of the lens elements may be selected to achieve quality optical performance and high image resolution in a small form factor telephoto camera.

  • Patent number: 8659823
    Abstract: Ring-field, catoptric and catadioptric, unit-magnification, projection optical systems having non-concentric optical surfaces are disclosed. Each system has a system axis with object and image planes on opposite sides of the system axis. The non-concentric surfaces allow for working distances of the object and image planes in excess of 100 millimeters to be achieved, with a ring-field width sufficient to allow a rectangular object-field having a long dimension in excess of 100 mm to be projected.
