摘要

The invention relates to an optical instrument engineering, namely to the lens and can be used as a video camera lens to form images on a CCD matrix. Lens pupil rendered comprises four components arranged in series on the optical axis. The first component - negative meniscus concave surface facing to the object space. The second component is formed as a biconvex lens. The third component is formed as a negative meniscus concave surface facing to the space of the image and a cemented lens of positive and negative. The fourth component - a positive lens. In this case, the positive lens of the third component is in the form of a meniscus facing a convex surface toward the object space, and the negative lens of the third component is formed as a meniscus. A positive fourth lens component is formed as a meniscus facing a convex surface toward the object space. Wherein the following relations: f 1 ': f 3' ≥1 φ2≥0,8φ, wherein f 1 '- focal distance of the first component, f 3' - focal distance of the third component, φ - optical power of the lens, φ 2 - the optical power of the second component. Lens rendered pupil has good image quality over the entire field of view, wherein the length of the lens from the first surface to the image plane is 70 mm, which is 1,303 of its focal length. 6 Fig.
