The invention relates to a 1.3mm focal length panoramic day and night confocal high-definition lens which includes a front group A with negative focal power, a light bar C and a rear group B with positive focal power, wherein the front group A, the light bar C and the rear group B are sequentially arranged in the incidence direction of light from front to rear. The front group A includes a negative meniscus lens A-1, a negative meniscus lens A-2 and a biconvex positive lens A-3 which are arranged in sequence from the front to the back, and the rear group B includes a glued group formed by closely connecting a positive meniscus lens B-1, a biconvex lens B-2 and a negative meniscus lens B-3 which are sequentially arranged from the front to the back. The 1.3mm focal length panoramic day and night confocal high-definition lens has the advantages of great viewing angle, high resolution, day/night dual purpose, optical structure simplification, and economical material cost and the like and can be adaptive with a 3000000 pixel high resolution CCD or CMOS.
