[0002] At present, the high-pixel lenses used in digital lenses generally have such shortcomings: the lens has large dimensions, small imaging area, and high cost.
At present, there are only a few lenses that improve certain aspects at the expense of other aspects. For example, in order to achieve large image height and high pixels, it is necessary to increase the size or increase the resolution, which increases the cost and cannot satisfy consumers’ demand for small lenses. Volume and high image quality requirements at the same time

Abstract
The invention relates to a high pixel optical system with small size and distortion. The optical system comprises a diaphragm, and is characterized in that a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens are arranged behind the diaphragm in sequence, wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens are all aspheric surface lenses, a chip sensitive to light is arranged behind the sixth lens, and the second lens and the fourth lens are glass lenses. According to the high pixel optical system with the small size and distortion, the six lenses are arranged to achieve optical imaging, and the optical system is simple in structure and small in size and distortion.
Description
【Technical field】 [0001] The present invention relates to optical systems. 【Background technique】 [0002] At present, the high-pixel lenses used in digital lenses generally have such disadvantages: the lens has a large size, a small imaging area, and high cost. At present, there are only a few lenses that improve certain aspects at the expense of other aspects. For example, in order to achieve large image height and high pixels, it is necessary to increase the size or increase the resolution, which increases the cost and cannot satisfy consumers’ demand for small lenses. There is a demand for high imaging quality while maintaining the volume. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an optical system with simple structure, small volume, small distortion and high pixel. [0004] In order to solve the above problems, the present invention adopts the following technical solutions: [...
