Miniaturized high-resolution fog-penetrating zoom lens

Abstract

The invention relates to a miniaturized high-resolution fog transmission zoom lens comprising a front fixed group A of positive focal power, a zooming group B of negative focal power, an automatic diaphragm, a rear fixed group C of positive focal power, a compensating group D of positive focal power and a color filter conversion component E, wherein the front fixed group A, the zooming group B, the rear fixed group C, the compensating group D and the color filter conversion component E are arranged in turn along a light incident direction. The miniaturized high-resolution fog transmission zoom lens is simple, reasonable and compact in structural design, high-resolution within the spectral range of 450nm-900nm, less in parts and components and low in processing cost so as to still have sufficient energy for imaging through the lens in case of rainy, snowy, mist and other special weather to output the high-quality image, and thus the monitoring capacity can be effectively enhanced.

Description

technical field [0001] The invention relates to a miniaturized high-resolution fog-penetrating zoom lens. Background technique [0002] Under special weather conditions such as rain, snow, and mist, the transmittance of the light band in the incident light decreases, resulting in dim video images, lower contrast, and lower definition, which easily leads to loss of picture details and blurred images, which seriously affects system performance. monitoring capabilities. To achieve good image quality under special weather conditions, it is necessary to increase the light passing through the lens to the imaging surface. Usually, the lens aperture is increased to increase the amount of light entering. However, large aperture lenses have limitations due to their low resolution, large size, and high cost. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a miniaturized high-re...

To have good image quality under special weather conditions, it is necessary to increase the light that reaches the imaging surface through the lens. Usually, the aperture of the lens is increased to increase the amount of light entering. However, the resolution of the large aperture lens is low, the volume is large, and the cost is high, so it has limitations.
