Abstract

The invention relates to a glass-plastic hybrid optical system, which comprises a first lens with negative focal power, a second lens with negative focal power, a third lens with positive focal power, a fourth lens with negative focal power, a fifth lens with positive focal power, a sixth lens, a seventh lens and an eighth lens which are sequentially arranged from an object side to an image side along an optical axis, the focal power of the sixth lens is positive, the focal power of the seventh lens is negative, the focal power of the eighth lens is positive or negative, and the fourth lens and the fifth lens form a glued lens group with positive focal power. The glass-plastic hybrid optical system has the advantages of small size, large imaging target surface, high resolution and no virtual focus at high and low temperatures.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a glass-plastic hybrid optical system. Background technique [0002] With the popularization of security monitoring technology, people have higher requirements for the size and resolution performance of monitoring equipment. Then, small size and high resolution are the unchanging themes in the development of monitoring equipment related products. In order to obtain a higher-resolution surveillance image, a chip with a larger imaging area is often required in surveillance equipment, so the lens that matches the chip is generally larger, which is contrary to the development vision of smaller surveillance equipment . Therefore, there is an urgent need in the market for a large number of high-resolution lenses that can achieve small size and large imaging target area. [0003] In response to the above requirements, the prior art CN201821269451.5 discloses an ultra-wide-ang...
