    摘要: A zoom lens includes, in order from an object side to an image side, first, second, third, and fourth lens groups with positive, negative, negative, and positive refractive powers, respectively. When varying magnification from a short focal length end to a long focal length end, the second lens group is moved to the image side, the third lens group is moved, and the first and fourth lens groups are fixed. The fourth lens group is constituted of a lens group on the object side and a lens group on the image side with a largest distance in the fourth lens group between them. Each of a refractive index, Abbe number, a partial dispersion ratio, and the like of each of at least one positive lens of the lens group on the object side and two positive lenses of the first lens group is regulated to be in a predetermined range.

    摘要: A scope includes an objective lens system having refractive power, a relay lens system having refractive power, and an eyepiece system having refractive power. The relay lens system includes a first, a second, and a third lens groups. The second lens group includes a II-2-1 lens and a II-2-2 lens, and both of which are cemented. The third lens group includes a II-3-1 lens having a convex surface facing an object side and a II-3-2 lens having a convex surface facing an image side, and both of which are cemented. The second lens group and the third lens group can move along an optical axis to change a magnification of the relay lens system and thereby change a magnification of the scope. The objective lens system, the relay lens system, and the eyepiece system are arranged in order from the object side to the image side along the optical axis.

    摘要: 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.
