More specifically, the system refers to a variety of electronic products such as mobile phones, p C /AM, laptops, etc. Or the miniature imaging lens set of the video equipment (including the photographing or imaging function), but mainly by the appropriate focal length, distance and length ratio of each lens, up to 90% | The novel creator of the best imaging effect . [Previous technology] According to the popularity of mobile communication devices, the current society is almost a human-supported mobile phone, or a portable computer or PDA, etc., so it is dedicated to this difficult product. The related micro-imaging lens set for taking pictures or imaging has also emerged in large numbers, and this creation is the main imaging mirror # group structure of this image mirror. Moreover, 'because such electronic products are light, thin, short, and small, in order to facilitate the main appeal of the carrying behavior, the requirements for the overall composition of the imaging lens group cannot be separated from these same requirements, in short In order to meet the soft and hard conditions of electronic product manufacturers and their specific products, the manufacturer of imaging lens sets must develop a set of matching imaging lens sets for their assembly, most of which cannot be All other products are suitable for use; therefore, it is difficult for such imaging lens group to arbitrarily cite any pre-existing case to compare and evaluate its superiority and inferiority in all aspects. 4 M314860 As mentioned above, the composition specifications (such as the overall size or resolution requirements) of the imaging lens group are strongly restricted by the electronic products that are desired to be combined, so at best, the number of lenses can only be used. To make a simple distinction, such as two, three, four or five-piece imaging lens sets, today, this creation is specifically for the four-piece imaging lens group. [New content] For this reason, the creator based on the above facts, especially for the so-called four-piece imaging lens group to give a significant improvement in the imaging effect, in the case of using the least space, in order to obtain the best expected effect It is the main purpose of this creation. Yes, it mainly comprises a fixed aperture and an optical lens set, and the optical lens set comprises first, second, third and fourth lenses; in particular, the suitable focal length and distance between the lenses are used The length ratio, which is the characteristic of achieving the best imaging effect. [Embodiment] In order to further understand the technical means and structural features of the creation, it is detailed in the following figure: ' First, as shown in the figure - the figure includes a fixed aperture 1〇 and - The optical lens group 20' includes the first lens, the second lens 22, the third lens 23 and the fourth lens 24, and the arrangement order is from the object side 30 to the image side 40: 5 M314860 The lens 21 is convex toward the object side 30, and is curved toward the image side 4; the fixed aperture 10; the second lens 22 is a curved surface facing the object side 30, and is concave toward the image side 4〇; the second lens The object side 30 is a concave surface, the image side is convex, and at least one surface is aspherical; the fourth lens 24 faces the object side 30 and the image side 40 to be corresponding concave, convex or convex, concave curved surface, and At least one side is aspheric. Further, the speaker 21 and the second lens 22 can be spherical or aspherical lenses. Furthermore, the imaging lens set must satisfy the following conditions: 0. 3< | fl | / | f | <3· 0, 0.3< | f2 I / | f | <3· 0, 0.3< F3 I / | f | <3· 0, 0.3< | f4 I / 1 f | <3· 0, 〇·〇< I D1 I / | TL | <0· 2 ; where, | fl | is the focal length value of the first lens 21, |f2| is the focal length value of the second lens 22, |f3| is the focal length value of the third lens 23, |f4| is the focal length value of the fourth lens 24, |f| The focal length value of the optical lens group 2 ' I D1 | is the distance between the first lens 21 and the aperture 1 on the optical axis, and the | hole | is the length of the optical lens group 20. The fox surface pointed by the lens 21, the second lens 22 and the fourth lens 24 may be convex or concave. 6 M314860 Yes, this creation is characterized by the appropriate focal length and length ratio of each of the above lenses to achieve the best imaging effect. Of course, after the fourth lens 24 is an imaging lens 25, but this is a must-have system for various types of imaging copper. It is not the characteristics of this _, so it will not be described, please forgive me. Looking at the above, before the application, the creation of this creation has not only been found in similar products and related publications, but also has the practical value of "newness" and "progress". Cheng has already met the application requirements of the new patent, and it is reasonable to obtain the patent law. Protection, 提出 apply in accordance with the law.
