New description: [New technical field] This creation is related to the structure of the imaging lens group (1). In more detail, the _ refers to the mobile phone, pda, PC CAM, Laptops, etc., all kinds of electronic products or video equipment, such as micro-imaging groups (including Gu or imaging Wei), but mainly by borrowing - group compounding through the role of 侃 侃 俾, to achieve the best achievement A novel creator like an effect. [Prior Art] According to the results, it is well known that due to the popularity of mobile track equipment, today’s society is a human hand-supporting mobile phone, or it is equipped with electronic communication products such as laptop computers or PDAs. A series of related micro-imaging lens sets for taking photos or images of electronic products have also emerged in large numbers, and this creation is the main imaging mirror group structure of the imaging lens group such as 〇b. Moreover, since such electronic products are light, thin, short, and small, in order to facilitate the main appeal of the portable behavior, the requirements for the overall composition of the imaging mirror are not inconsistent with these same requirements, in short Therefore, the manufacturer of the imaging lens group, the soft and hard conditions of the electronic product manufacturers and their specific products, must be specially developed for them to match the imaging lens group for assembly and use. Township can not be applied to other products; therefore, it is difficult for such imaging lens group to arbitrarily cite any pre-existing case to make it better than its superiority and inferiority. Ming clock. 4 M313780 - As mentioned above, the composition specifications (such as the overall size, resolution, resolution requirements, etc.) of the imaging lens group are strongly limited by the electronic products that are desired to be combined, so the number of lenses can only be used at best. The simple distinction is made, such as two, three, four or five-piece imaging lens sets. Today, this creation is an innovative work for the four-piece imaging lens set. [New content] Φ For this reason, the creator is based on the above facts, especially for the so-called four-piece imaging lens group to provide significant improvements in the correction of chromatic aberration, in the case of using the least space, in order to find the best The imaging effect is the main purpose of this creation. Yes, the main method comprises a fixed aperture and an optical lens set, and the optical lens set comprises first, second, third and fourth lenses; and the second and fourth lenses are bonded together. The composite lens, by virtue of this - the composite lens has a special effect of correcting the chromatic aberration, and achieving the best imaging effect is a feature. [Embodiment] In order to further understand the technical means and structural features of the creation, the following is a detailed description of the following: First, as shown in the first figure, the system includes a fixed aperture 1〇 and An optical lens set 20, and the optical lens set 2 (4) includes a first lens, a second lens 23, a third lens 23 and a fourth lens 24, which are arranged from the object side 30 to the image side 4: 5 M313780 ' The first lens 21 is convex toward the object side 3G, concave surface toward the image side 4Q, and at least one surface is aspherical; the fixed aperture 10; the second lens 22 faces the object side 30 as a curved surface, facing the image side 4〇 is a convex surface and at least one side is aspherical; the third lens 23 is a f-moon negative lens whose absolute value of the radius of curvature toward the image side 4〇 is larger than the absolute value of the radius of curvature toward the object side 30; The fourth lens 24 is a positive lens which has a curved surface toward the image side 40, and its absolute value of the curvature radius toward the image side 4G is smaller than the absolute value of the curvature radius toward the object side 3 (). Further, the third lens 23 and the fourth lens 24 are a composite lens formed by bonding. Furthermore, the imaging lens set must satisfy the following conditions: ······················ I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I f4 I / I f I <20; wherein I fl I is the focal length value of the first lens 21, I row I is the focal length value of the second lens 22, and I f4 I is the focal length value of the fourth lens %, I is the focal length value of the optical lens group 20. The curved surface of the second lens 22 facing the object surface may be convex or concave. The curved surface of the fourth lens 24 toward the image plane may also be convex or concave.
