Problems solved by technology

Passive protection technology is to use tantalum sheets and other protective optical devices to increase its radiation resistance, but this will greatly increase the load weight, and the aircraft has very strict requirements on the load weight, because if the load weight increases by 1kg, the launch system will increase by several hundred kilograms , costly

Abstract

The invention relates to a radiation-resistant high-resolution space-borne camera lens, which comprises a front lens group, a diaphragm and a rear lens group arranged in sequence along the light incident direction, and the front group lens group consists of flat glass, a first meniscus positive lens , the second meniscus positive lens, the third meniscus positive lens, the first meniscus negative lens, the rear lens group is composed of the second meniscus negative lens, biconvex positive lens, the third meniscus negative lens, the fourth Meniscus positive lens composition. The lens is not only simple in structure and small in size, but also resistant to shock and vibration, high temperature difference and strong radiation in space.

Description

technical field [0001] The invention relates to a radiation-resistant high-resolution spaceborne camera lens. Background technique [0002] With the upsurge of the development of global space resources, the human race for the outer space of the earth is intensifying, and countries all over the world spare no effort to compete and control it. The detection and monitoring of space targets plays a key role in this space battle, and the development of space camera optical systems has become an important topic for researchers in this field. Developed countries have strictly blocked such technologies, and our country can only rely on independent research and development. Anti-radiation technology generally includes passive protection technology and active protection technology. Passive protection technology is to use tantalum sheets and other protective optical devices to increase its radiation resistance, but this will greatly increase the load weight, and the aircraft has very...
