Miniaturized high-resolution fog-penetrating camera lens

Abstract

The invention relates to a miniaturized high-resolution fog-permeable camera lens. The optical structure of the lens is respectively provided with a front group A with a positive focal power, an iris assembly B, Rear group C with positive refractive power and color filter conversion assembly D, the front group A is sequentially provided with positive crescent lens A-1, negative crescent lens A-2, biconvex lens A-3 and biconcave lens A- 4. The first cemented group that is closely connected and the second cemented group that is closely connected by biconvex lens A-5 and biconcave lens A-6. The rear group C is sequentially provided with biconvex lens C-1 and biconvex lens C-2. The lens can not only provide photoelectric signals for 1 / 1.8″ high-resolution CCD or CMOS cameras in a good weather environment, and produce high-definition video images of no less than 3 million pixels, but also can achieve high-definition video images in rainy days, snowy days, mist, etc. Monitoring of long-distance targets under cloudy weather conditions.

Description

technical field [0001] The invention relates to an optical camera device of high-definition video technology, in particular to a miniaturized high-resolution fog-penetrating camera lens. Background technique [0002] With the continuous emergence of high-resolution CCD and CMOS image sensors, photoelectric video surveillance has entered the high-definition era. Due to the small wavelength λ of the visible light spectrum, the existing high-definition camera lenses for conventional long-distance monitoring will reduce the transmission ability of incident light in complex weather conditions, especially in hazy weather conditions such as rain, snow, and mist, resulting in image contrast, The decrease in definition shortens the monitoring distance and seriously affects the monitoring capability of the system. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to b...
