This vehicle-mounted pick-up camera lens, comprises lens barrel, the balsaming lens that is provided with successively meniscus, the first biconvex lens along lens barrel front end to lens barrel rear end and consists of the second biconvex lens and recessed plano lens gummed in described lens barrel; Between described meniscus and the first biconvex lens, be provided with diaphragm, between described the first biconvex lens and balsaming lens, be provided with spacer ring.
The concave surface of described meniscus is relative with described the first biconvex lens one side, and the convex surface of the second biconvex lens that forms described balsaming lens is relative with described the first biconvex lens opposite side.
Described meniscus convex curvature radius is 0.052mm, and described meniscus concave curvature radius is 0.1641mm; Two convex curvature radiuses of described the first biconvex lens be respectively 0.044mm and-0.044mm; The side convex curvature radius that described the second biconvex lens is relative with described the first biconvex lens is 0.044mm, and described the second biconvex lens opposite side convex curvature radius is 0.122, and the concave curvature radius of described recessed plano lens is-0.122.
Described balsaming lens is fitted in described lens barrel by trim ring.
Described trim ring is that inwall is the annular element of the conical surface.
The utility model has the advantage of: this vehicle-mounted pick-up camera lens, meniscus, the first biconvex lens and the balsaming lens being formed by the second biconvex lens and recessed plano lens gummed, can allow visible ray and near infrared light image planes after this optical lens overlap, no matter be visible ray or near infrared light, its imaging is all clear, the real function of vehicle-mounted camera day and night.This vehicle-mounted pick-up camera lens, the optical signature that can reach is focal length F=16mm, field of view angle 2W=30, F/#=2.0 back focal length LF is more than 10mm, except energy day and night, can also reach 1,000,000 grades of pixels, clear picture, discernment is higher, can meet people's request for utilization.
