Abstract

The invention provides a large-aperture high-resolution optical lens. The large-aperture high-resolution optical lens comprises a first meniscus negative lens, a second biconvex positive lens, a third biconvex positive lens and a fourth meniscus negative lens which are sequentially arranged from left to right along a light incident light path. By adopting a 1G3P structure, the size and the quality of the whole system are reduced while the manufacturing cost is controlled. The large-aperture and small-F-number design is adopted, so that the system has higher imaging quality and more excellent complex lighting environment adaptability. Meanwhile, the system has the characteristic of low temperature drift in the temperature range of-40 DEG C to 85 DEG C, and the imaging stability of the system is further improved. In addition, the imaging quality is excellent, and the 4K camera shooting requirement can be met.

Description

technical field [0001] The invention relates to a large-aperture high-resolution optical lens. Background technique [0002] Security lenses play a vital role in maintaining social order and protecting the property safety of the country, enterprises and people. In recent years, with the gradual diversification of security lens usage scenarios, customers have begun to put forward higher requirements for the optical performance and optical-mechanical structure stability of the lens. However, most security lenses on the market today are difficult to meet the requirements of high resolution, small size, high stability and cost control at the same time, resulting in the performance bottleneck of the optical system. Contents of the invention [0003] The invention provides a large-aperture high-resolution optical lens and an imaging method thereof, and provides an improvement solution for the above-mentioned technical problems. The 1G3P structure is used to reduce the size and...
