Large-view-field optical imaging lens and optical system formed by same

Abstract

The invention provides a large-view-field optical imaging lens and an optical system formed by the same. The large-view-field optical imaging lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens and an optical filter which are sequentially arranged in the light propagation direction. The first lens, the second lens and the eighth lens are meniscus lenses respectively, the third lens and the sixth lens are biconcave lenses respectively, and the fourth lens, the fifth lens and the seventh lens are biconvex lenses respectively. Compared with a traditional spaceborne lens, the large-view-field optical imaging lens and an optical system formed by the large-view-field optical imaging lens have the advantages of being high in resolution ratio, small in size, low in weight and the like, the imaging quality of the optical system reaches up to 26,000,000 pixels, the imaging spectrum is wide, the view field angle is large, the large-view-field optical imaging lens can adapt to the severe environment when a satellite is launched and runs on an orbit, the imaging lens also has the advantages of shock and vibration resistance, space high temperature difference resistance, strong radiation and the like, overcomes the complexity of a space environment, and meets the space use requirements of aerospace engineering.

Description

technical field [0001] The invention relates to the technical field of optical design, in particular to a large field of view, high-resolution optical imaging lens and an optical system formed therefrom. Background technique [0002] With the increasingly intensified competition for space resource development, the development of high-resolution space target detection systems has become the key to the competition. The core component of the detection system is the target detection lens, which is mainly used in the detection and tracking of space targets and debris. For this reason, the successful development of the high-resolution miniature spaceborne camera optical system has played an important role in improving my country's ability to monitor near-Earth space targets. The first use of CCD cameras as spaceborne earth observation payloads was in the early 1980s. The space-borne camera as an earth observation instrument was really valued by people and entered the practical s...
