Large-field-depth large-view-field wide-temperature-variance high-image-quality optical system

Abstract

The invention relates to a large-field-depth large-view-field wide-temperature-variance high-image-quality optical system. A first negative lens, a second negative lens, a first positive lens, a third negative lens, a diaphragm, a second positive lens, a third positive lens, a fourth positive lens and a fourth negative lens which are successively arranged on an optical path. The large-field-depth large-view-field wide-temperature-variance high-image-quality optical system provided by the invention facilitates correction of field curvature, effectively resists complex particle irradiation in space, prevents degumming in a complex space environment and is applied to space environment.

Description

technical field [0001] The invention relates to the field of optics, in particular to an optical system with large depth of field, large field of view, wide temperature and high image quality. Mainly used for space rendezvous and docking optical imaging sensors, robotic arm hand-eye optical cameras and lunar rover visual navigation cameras, etc. It can also be applied to fields requiring a large depth of field optical system, such as civilian machine vision and security monitoring equipment. Background technique [0002] With the rapid development of my country's national economy and defense industry technology, the demand for spacecraft is increasing day by day, and the requirements for its capabilities are increasing day by day. With the rapid development of space technology fields such as space station orbit service and deep space exploration, the demand for space manipulator technology and rendezvous and docking technology is becoming more and more urgent, and the requi...
