Abstract

The invention discloses a high-definition 4K panoramic lens system, and belongs to the technical field of lenses. The high-definition 4K panoramic lens system comprises a lens front set and a lens rear set which are sequentially arranged in the light incidence direction, a diaphragm is arranged between the lens front set and the lens rear set, the lens front set comprises a first lens, a second lens and a third lens which are sequentially arranged in the light incidence direction, and the lens rear set comprises a fourth lens, a fifth lens and a sixth lens which are sequentially arranged in the light incidence direction. The high-definition 4K panoramic lens system has the characteristic of low cost while high resolution, large relative aperture, day and night co-focus and low distortion are met.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a high-definition 4K panoramic lens system. Background technique [0002] At present, there are a variety of fixed-focus lenses used in monitoring systems in the market, and the emergence and application of small TV monitoring cameras have a history of 20 to 30 years. There are various types of miniature camera lenses to match them . Their performance indicators are mixed, most of them are low-end products, and their performance indicators are low. Although some can meet the requirements of high-definition, there are many defects in high-definition and wide-angle monitoring in small spaces. Day and night confocal, low distortion and other advantages, often require higher cost, and the spectral range to adapt to is narrow, can only be used under daylight conditions of 480nm ~ 700nm, the image distortion is large, and the image distortion is different from the real scene Big, poor ...
