Low-chromatic-aberration compact video lens with focal length of 16mm

The invention discloses a low-chromatic-aberration compact video lens with a focal length of 16mm. The low-chromatic-aberration compact video lens comprises a first lens group and a second lens group which are sequentially arranged along a light incidence direction, the first lens group is a fixed group, and the focal power is positive; the second lens group is a focusing group, and the focal power is positive; the first lens group comprises six lenses, the second lens group comprises eight lenses, and an iris diaphragm is arranged in the second lens group; the first lens group and the second lens group satisfy the following formula: 1.3 lt; f2/f1lt; 2, 3; wherein f1 represents the focal length value of the first lens group, and f2 represents the focal length value of the second lens group. According to the invention, 16mm short focal length, large aperture, high resolution, small dispersion, small distortion and short total length are realized. 本发明公开了一种焦距为16mm的低色差紧凑型视频镜头，包括：沿光线入射方向依次包括第一透镜组、第二透镜组，第一透镜组为固定组，光
