Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a zoom lens system. [Prior Art] [0002] In recent years, with the development of multimedia, there is an increasing demand for digital imaging devices such as CCD (Charged Coupled Device) or CMOS CComplementary Metal Oxide Semiconduct- 〇r) as imaging elements. The process technology of these solid-state imaging devices, such as CCD or CMOS, has been improved, and it has been possible to produce imaging devices with a size of only a few micrometers per pixel. Therefore, the 丨 zoom lens system that is compatible with the above imaging device is required to be miniaturized. [0003] [0005] [0005] 099137065 zoom lens system miniaturization approach - is to increase the zoom ratio, but the existing zoom lens system, when the zoom ratio is higher, the aberrations become difficult to continue ' Thereby, the zoom lens f system is poor in image quality while satisfying miniaturization. [...] [Invention] In view of the above, it is necessary to provide a zoom lens system that satisfies miniaturization while having better imaging quality. a zoom lens system 'including a positive lens group, a second lens group having a negative power, a third lens group having a positive power, and a third lens group having a positive power from the object side to the side of the money, a fourth lens group of positive refractive power and an imaging surface, wherein the first lens group and the third lens group are along the optical direction of the zoom process, (4) the second lens group and the fourth lens The group moves along the optical axis during zooming. The zoom lens form number qing! Page 4 of 3 page 09920 201217830 The system satisfies the conditional expression 5<f3/f4<8. 2; 2. 1<U2Mw|<3.2, where 'mid' f2 is the effective focal length of the second lens group; F3 is the effective focal length of the third lens group; ί 4 is the effective focal length of the fourth lens group; fw is the effective focal length of the zoom lens system in the wide-angle end state. [〇〇〇6] In the case where the conditional expression is satisfied, the zoom lens system has a length of a shorter 0' to satisfy the miniaturization of the zoom lens system while ensuring the optical focus of the second, third and fourth lens groups. Degree in the zoom lens system to reduce spherical aberration and improve image quality. [Embodiment] [0007] The present invention will be further described in detail below with reference to the accompanying drawings. Please refer to FIG. 1, which is a zoom lens system 100 provided by the present invention. A first lens group 10 including a positive refractive power, a negative optical power 蚱 second lens group 20, an aperture 50, and a positive light are sequentially included from the object side to the image side direction along the optical axis of the zoom lens system 1〇〇. A third telescope group 30 of power, a fourth lens group 40 of positive power, and a calender sheet 60. The zoom lens system 100 has an imaging surface 70 on the image side. 0009 [0009] When the zoom lens system 100 is used for imaging, light from a subject is incident from the object side direction into the zoom lens system 100 and sequentially passes through the first lens group 10 and the second lens group 20 The aperture 50, the third lens group 30, and the fourth lens group 40 are finally collected by the filter 60 onto the imaging surface 70 by placing a solid imaging device such as a CCD or CMOS on the imaging surface 70. At that point, you can get an image of the subject. When the zoom lens system 100 performs a zooming operation, the first lens group 10 is fixed in the optical axis direction, the second lens group 20 is moved along the optical axis, and the third lens group 30 is fixed in the optical axis direction. The fourth lens group 40 moves along the optical axis to compensate for the change of the position of the imaging surface caused by the zoom process and the change of the object distance by adding 099137065 Form No. A0101 Page 5 / Total 30 Page 0992064643-0 201217830. Further, when the zoom lens system 100 is switched from the wide-angle state to the telephoto state, the interval between the second lens group 20 and the first lens group 10 is increased. In the present embodiment, the first lens group 10 includes, from the object side to the image side, a first lens 11, a second lens 12, a third lens 13, and a fourth lens 14. Wherein the first lens π is a concave meniscus lens having a convex surface facing the object side, the second lens 12 is a convex lens, and the first lens 11 and the second lens 12 are glued together to form a cemented lens. The third lens 13 is a convex meniscus lens having a convex surface facing the object side, and the fourth lens 14 is a spherical glass lens having a convex surface, and the fourth lens 14 is a convex surface facing the object side. Meniscus glass lens. By adding the fourth lens 14 of the spherical glass after the first lens 11, the second lens 12, and the third lens 13, it is possible to appropriately compensate for the occurrence of the first lens group 1 〇 in the intermediate focal length state and the telephoto state. The spherical aberration is effective to improve the image resolution capability of the zoom lens system 100. [0011] The second lens group 20 includes a fifth lens 21, a sixth lens 22, and a seventh lens 23 in this order from the object side to the image side. The fifth lens 21 is a concave meniscus lens having a convex surface facing the object side, and the sixth lens 22 is a negative power lens. The seventh lens 23 is a positive power lens. The sixth lens 22 and the seventh lens 23 are glued together to form a cemented lens. [0012] In order to achieve a low height and a low spherical aberration of the entire zoom lens system 100, the zoom lens system 100 satisfies the following conditional expression: [0013] (1) 5 <f3/f4<8. 2; and 099137065 No. A0101 Page 6/Total 30 Page 0992064643-0 201217830 [0014] [0015] [0018] [0020] [0020] (2) 2.I<|f2/fw|< 3.2, f2 is the effective focal length of the second lens group 20; f3 is the effective focal length of the third lens group 30; f4 is the effective focal length of the fourth lens group 40; fw is the zoom lens system 100 Effective focal length in the wide-angle end state. Since the third lens group 30 in the zoom lens system 100 has too small a power to cause a spherical aberration to be sufficiently compensated, the fourth lens group 40 is too small to cause a moving distance when the fourth lens group 40 is zoomed. Too long is not conducive to shortening the total length of the lens, and the back focus of the telephoto end will be too short. In addition, the optical power of the second lens group 20 in the zoom lens system 100 causes the assembly sensitivity to be too large, and the analysis is greatly reduced due to factors such as assembly eccentricity, if the second lens group 20 is optically pleasing. Too small will cause the second lens group 20 to move too long when zooming, which is not conducive to shortening the total length of the lens. The condition (1) and the conditional expression (2) respectively show the relationship between the effective focal length of the third lens group 30 and the focal length of the fourth lens group 40, and the second lens group 20 and the The relationship between the effective focal lengths of the zoom lens system 100 in the wide-angle end state can be ensured that the zoom lens system 100 can improve the imaging quality while reducing the overall length of the zoom lens system 100 while defining the above two conditional expressions. . Preferably, the first lens group 10 satisfies the conditional expression: (3) 70 <V2; wherein V2 represents the Abbe number of the second lens to better correct lateral chromatic aberration in the telephoto state. Preferably, the second lens group 20 further satisfies the conditional expression: (4) 0·2 < M2/L <0.4; 099137065 Form No. A0101 Page 7 / Total 30 Page 0992064643-0 201217830 _1] Where M2 is a zoom lens The maximum amount of movement of the first lens group along the optical axis when the system is switched from the wide-angle state to the telephoto state, L is the total length of the zoom lens system, that is, the distance from the surface of the first lens 11 near the object side to the imaging surface 70. Since the lens of the high zoom ratio is too short when the second lens group 2 is zoomed, the power of the second lens group 2〇 must be increased, resulting in an increase in assembly sensitivity. If the moving distance is too long, on the one hand, the total length of the zoom lens system 100 is increased, and on the other hand, the amount of change in the curvature of field and the spherical aberration during zooming is increased. By the above conditional expression (4), the assembly sensitivity of the zoom lens system 100 can be reduced, the length of the zoom lens system 1〇〇 can be reduced, and the amount of change in field curvature and spherical aberration at the time of zooming can be reduced. [0022] The third lens group 30 is an eighth lens, the third lens group 30 is a convex meniscus lens with a convex surface facing the object side, and the third lens group 3〇 includes at least one formed by an aspheric surface. s surface. In the present embodiment, the third lens group 30 includes two surfaces formed by aspherical surfaces, which can eliminate spherical aberration, coma, and astigmatism, and improve image quality. Preferably, the third lens set 30 employs a plastic lens to reduce the cost of the lens system 100. The fourth lens group 40 includes, in order from the object side, a ninth lens 41, a tenth lens 42, and an eleventh lens 43 in this order. The ninth lens 41 is a positive power lens, and the ninth lens 41 includes at least one surface formed by an aspherical surface. In the present embodiment, the ninth lens 41 includes two surfaces formed by aspherical surfaces, so that spherical aberration, coma, and astigmatism can be eliminated, and the image quality can be improved. The tenth lens 42 is a negative power lens, the eleventh lens 43 is a positive power lens, and the tenth lens 42 and the eleventh lens 43 are glued together to constitute a cemented lens. Since the ninth lens 41 is not glued to the tenth lens 42 and the eleventh lens 43, 099137065 Form No. A0101 Page 8/Total 30 Page 0992064643-α 201217830 [0024] [0025] [0027] [0030] [0030] The risk of product scrapping due to inaccurate gluing in the gluing step can be reduced. Preferably, the first lens group 20 satisfies the conditional expression: (5) 45 < (V6 - V7) ' where V6, V7 represent the Abbe number of the sixth and seventh lenses, to be better Correct the lateral chromatic aberration in the telephoto state. The aperture 50 is located between the second lens group 20 and the third lens group 3〇 to restrict the light flux passing through the first lens group of the second lens group 20 into the third lens group 30, and let The second translucent: the light cone after the 20th can be more symmetrical, so that the coma of the zoom lens system 100 can be corrected. Preferably, the aperture 50 is disposed on a surface of the third lens group 30 near the object side, so that the number of components of the zoom lens system 100 can be reduced, and the complexity of assembly of the zoom lens system 100 is low. In actual operation, the reference surface-peripheral annular region on the object side of the third lens group 30 is directly blacked out as a light idle 50. The filter 60 is located in the $4 lens group 40. Between the image surface 70 and the image surface 70, it is mainly used to filter out the light in the infrared band in the light of the zoom lens system. It can be understood that the second lens group 2 of the zoom lens system 100 and the lens group 40 are made of a low dispersion material. In the present embodiment, each of the first lens group 20 and the fourth lens group 40 is made of glass. 2 to 10, the zoom lens system 1 本 本 of the present invention will be described in detail with reference to the specific embodiments. In the following embodiments, the third lens group 30 and the ninth lens 41 099137065 Form No. 1010101 Page 9 of 30 The two surfaces of 201217830 are aspherical.
