[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention provides an intelligent traffic lens with a large target surface, large light transmission and high resolution, which comprises, in order from the object side to the image side along the optical axis: a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixth lens L6, an aperture C, a seventh lens L7, an eighth lens L8, a ninth lens L9 and a tenth lens L10.

[0040] Among them, the first lens L1, the fourth lens L4, the fifth lens L5, the sixth lens L6, the seventh lens L7, the eighth lens L8 and the tenth lens L10 have positive refractive power; the second lens L2, the third lens L3 and the ninth lens L9 have negative refractive power; the eighth lens L8 and the ninth lens L9 are cemented together to form a cemented member; the first lens L1 to the sixth lens L6 constitute a front lens group; the seventh lens L7 to the tenth lens L10 constitute a rear lens group.

[0041] The first lens L1 is a double convex positive lens or a meniscus positive lens with the convex surface facing the object. This shape is conducive to the lens obtaining light with a wider field of view.

[0042] The second lens L2 compresses the light collected by the first lens L1, which helps to make the brightness of the picture more uniform.

[0043] The third lens L3 diverges the light collected by the second lens L2, allowing the light to smoothly transition to the rear optical system and reasonably controlling the optical power.

[0044] The fourth lens L4 can focus the light collected by the third lens L3 and correct the aberration to optimize the imaging performance of the lens group.

[0045] The fifth lens L5 can focus the light collected by the fourth lens L4 so that the light is more evenly irradiated to the target area.

[0046] The sixth lens L6 can compress the light collected by the fifth lens L5, so that the light can smoothly transition to the rear optical system, which is conducive to more uniform brightness of the picture.

[0047] The aperture C is placed between the sixth lens L6 and the seventh lens L7 to control the imaging quality and the performance of the optical system by limiting the range and direction of light passing through.

[0048] The seventh lens L7 can compress the light collected by the sixth lens L6, so that the light can be smoothly transferred to the rear optical system, which is conducive to more uniform brightness of the picture.

[0049] The eighth lens L8 and the ninth lens L9 are glued together to form a glued part, which is used to eliminate or balance the chromatic aberration and distortion produced by the lens and reduce the tolerance sensitivity. In addition, the eighth lens L8 and the ninth lens L9 are both glass lenses, which can effectively improve the stability and durability of the lens group.

[0050] The tenth lens L10 can focus the light collected by the cemented lens, which is beneficial to the field correction of the lens and optimizes the imaging performance of the lens group. Example 1

[0051] In the optical system of this example, the first lens L1 is a biconvex positive lens, the second lens L2 is a meniscus negative lens with the convex surface facing the object, the third lens L3 is a biconcave negative lens, the fourth lens L4 is a meniscus positive lens with the convex surface facing the image, the fifth lens L5 is a biconvex positive lens, the sixth lens L6 is a meniscus positive lens with the convex surface facing the object, the seventh lens L7 is a biconvex positive lens, the eighth lens L8 is a biconvex positive lens, the ninth lens L9 is a biconcave negative lens, and the tenth lens L10 is a biconvex positive lens. The optical path diagram of the traffic lens is shown in Figure 1 shown.

[0052] See Table 1, which lists the relevant parameters of each lens in this example, including the radius of curvature, thickness, refractive index of the material, and Abbe number:

[0053] Table 1

[0054]

[0055] Infinity means infinity.

[0056] In this example, the air distance from the first lens L1 to the second lens L2 is 0.1200 mm; the air distance from the second lens L2 to the third lens L3 is 7.9015 mm; the air distance from the third lens L3 to the fourth lens L4 is 5.1404 mm; the air distance from the fourth lens L4 to the fifth lens L5 is 0.1723 mm; the air distance from the fifth lens L5 to the sixth lens L6 is 0.2209 mm; the air distance from the sixth lens L6 to the aperture C is 10.9001 mm; the air distance from the aperture C to the seventh lens L7 is 4.2082 mm; the air distance from the seventh lens L7 to the eighth lens L8 is 0.1194 mm; the air distance from the ninth lens L9 to the tenth lens L10 is 4.5172 mm, and the air distance from the tenth lens L10 to the image plane IMG is 10.9931 mm.

[0057] The technical indicators achieved by the optical system in this example are as follows:

[0062] 5) The distance between the aperture C and the image plane of the sixth lens L6: D = 10.9001 mm;

[0063] 6) Total optical length of traffic lens: TTL = 81.4762mm;

[0064] 7) The radius of curvature of the object side of the fifth lens L5: R 51 =75.7900mm;

[0065] 8) The radius of curvature of the image side of the fifth lens L5: R 52 =-27.3820mm;

The MTF curves under each field of view decrease gently and have good consistency. It can be seen from the graph that the MTF value of the edge field of view at the spatial frequency of 60pl / mm is greater than 0.5, which means that the lens has good imaging effect and resolution in the full field of view.
