It can be applied to the motion DV and drive recorder of super large target surface requirement.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of big target surface motion of new high-resolution
Organized before DV tiny lens optical systems, including the lens set set gradually along light incident direction and group after lens set, the eyeglass
It is provided with diaphragm before group after group and lens set between group, group includes the set gradually along light incident direction before the lens set
One lens, the second lens and the 3rd lens, first lens, the second lens and the 3rd lens be respectively curved month type negative lens,
Double concave type negative lens and biconvex positive lens, first lens and the second lens at intervals of 2.52mm, second lens
With the 3rd lens at intervals of 0.83mm, the 3rd lens and diaphragm at intervals of 0.05mm；Group includes after the lens set
The 4th lens, the 5th lens and the 6th lens set gradually along light incident direction, the 4th lens, the 5th lens and
Six lens are respectively double concave type negative lens, biconvex positive lens and biconvex positive lens, the 4th lens and the 5th lens glue
Synthesize one group of gluing part lens, the diaphragm and glued part lens are at intervals of 1.2mm, glued part lens and the 6th saturating
Mirror at intervals of 0.1mm.
Preferably, it is first saturating described in the big target surface motion DV tiny lens optical systems of above-mentioned new high-resolution
Mirror, the second lens, the 3rd lens, the 4th lens, the radius of curvature R 1 and R2, light refractive index of the 5th lens and the 6th lens
Nd, Abbe number Vd and lens thickness D meet successively along light incident direction：
,
Compared with prior art, the utility model has the advantage of：The utility model optical system uses spherical design, work
Skill performance is good, and material cost is low.The system is made up of 6 eyeglasses, and positive negative power combination improves resolution ratio, and lens materials are selected
Height refraction, the optical glass material of low dispersion, solve various aberrations and the distortion of optical lens, make camera lens realize full filed,
High-resolution.The utility model not only has 1/2.3 super large target surface, while resolution ratio reaches 8 mega pixels, and can realize day
Night is dual-purpose, can be applied to the motion DV and drive recorder of super large target surface requirement.
