Super wide angle mega pixel vehicle-mounted lens

The invention relates to a super wide angle mega pixel vehicle-mounted lens, comprising two lens groups and diaphragm, wherein, starting from an object space, a front lens group with negative focal power, the diaphragm and a rear lens group with positive focal power are sequentially arranged. The front lens group comprises a first and a second lenses with negative focal power and a third lens with positive focal power; and the rear lens group comprises a glued lens plate group and a sixth lens with positive focal power. The second and the sixth lenses are aspherical lens plates, and at least one face includes an aspherical mirror face. The invention can realize super wide angle, large relative aperture and low distortion, still have high light permeability and definition in the temperature range from minus 40 DEG C to plus 85 DEG C, and is especially suitable for outdoor monitoring and a vehicle-mounted camera system under adverse environment.
