The present invention is described in detail below with reference to the drawings and the specific embodiments, which are not repeated herein, but the embodiments of the present invention are not limited to the following embodiments.
Referring to fig. 1, the imaging lens of the present invention includes a first lens group 1, a diaphragm 2, and a second lens group 3 sequentially arranged from an object side to an image side along an optical axis, where the first lens group 1 includes at least five lenses, the second lens group 3 includes four lenses, the first lens group 1 is a fixed group, and the second lens group 3 is a focusing group. The first lens group 1 has positive focal power or negative focal power, the second lens groups 3 have positive focal power, and when imaging from infinity to a close distance, the second lens group 3 moves along the optical axis direction for focusing. The image side of the second lens group 3 is also provided with a filtering/color filter, and the image surface 4 is positioned at the image side of the filtering/color filter. The first lens group 1 at least comprises two negative lenses and two positive lenses, and the second lens group 3 comprises one negative lens and three positive lenses. The first lens group 1 is used as a fixed group and mainly plays the roles of turning a light path and expanding an aperture, so that light rays smoothly enter an imaging system under the condition of ensuring the size of the aperture, the tolerance sensitivity of the system is further reduced, and then a plurality of positive and negative lenses are matched to facilitate the correction of the high and low temperatures of the system. The second lens group 3 is used as a focusing lens group, and mainly has the functions of enabling the optical system to clearly image at different object distances, correcting monochromatic aberration of the system, ensuring consistency of image quality under a low distortion condition, and correcting chromatic aberration to ensure good color rendition.
In the first lens group 1, the lenses closest to the object side and the image side are both concave and convex, wherein the object side surface of the lens located at the object side is convex, and the image side surface of the lens located at the image side is concave. One of the two negative lenses of the first lens set 1 is of a biconcave type, and the other negative lens of the first lens set is of a convex-concave type. Therefore, the first lens group 1 adopts a plurality of positive and negative lenses to match with each other, so that the high and low temperatures of the system can be corrected conveniently, and adopts a plurality of concave-convex lenses to correct the aberration of the system conveniently, so that the tolerance sensitivity of the imaging system is reduced, and the image definition is improved.
In the present invention, the second lens group 3 includes three biconvex lenses and one biconcave lens, and has a cemented lens group. Therefore, the second lens group 3 is favorable for correcting monochromatic aberration and chromatic aberration of the whole group of the second lens group 3 by adopting the power matching of the positive lens and the negative lens and the use of the adhesive sheet, so that the tolerance sensitivity of the optical system can be reduced, and the imaging quality of the optical system can be improved.
In the present invention, the focal length F1 of the first lens group 1 and the focal length F of the imaging lens satisfy the following relational expression: -20< F1/F < 20. Therefore, by reasonably matching the positive and negative focal powers and the focal power of the first lens group 1 and the whole lens, low distortion and reduced tolerance sensitivity can be well ensured. The focal length F2 of the second lens group 3 and the imaging lens focal length F satisfy the following relational expression: 1< F2/F < 2. Therefore, by reasonably matching the positive and negative focal powers and the focal powers of the second lens group 3 and the whole imaging lens, the deterioration of focusing performance under different object distances can be well avoided, and the tolerance sensitivity is easily reduced. The total length L of the imaging lens (namely the distance from the first lens to the image plane) and the focal length F of the imaging lens satisfy the following relational expression: 2< L/F < 8. Therefore, the total length of the system is reasonably controlled, the volume of the whole lens can be balanced to control the cost, the imaging quality of the optical system is ensured, and the image quality contrast is high. One lens in the cemented lens group of the second lens group 3 is made of a low dispersion glass material, and the refractive index ND and the abbe number VD thereof respectively satisfy the following relations: ND is more than or equal to 1.40 and less than or equal to 1.53; VD is more than or equal to 64 and less than or equal to 96. One of the lenses of the second lens group 3, which is a cemented lens, is made of a low dispersion material, which is beneficial to correcting chromatic aberration, and can avoid the deterioration of focusing performance under different object distances, and is easy to correct high and low temperature performance.
In summary, the imaging lens provided by the invention has the advantages that the imaging lens is finer and smoother in imaging, the dynamic imaging range is wider, the depth of field is larger, the color and the contrast are also good, the high-low temperature performance is better, the application range is wider, and meanwhile, the visual field of the lens is wider due to the smaller distortion characteristic of the lens.
