1.2 inch intelligent traffic monitoring system lens and working method thereof

Abstract

The application discloses a 1.2-inch intelligent traffic monitoring system lens and a working method thereof. An optical imaging system of the lens is sequentially provided with first to fourteenth lenses from an object side to an image side. The optical power of each lens is in a positive-negative combination form, which greatly reduces spherical aberration and other optical aberrations. The fourth lens and the fifth lens are achromatic double cemented lens groups, the seventh lens and the eighth lens are achromatic double cemented lens groups, the ninth lens and the tenth lens are achromatic double cemented lens groups, and the eleventh lens, the twelfth lens and the thirteenth lens are achromatic triple cemented lens groups. Reasonable lens collocation enables the optical system to realize large aperture, large target surface, day and night non-defocusing, and good correction of on-axis and off-axis aberrations, so that the lens has good imaging quality.
