Description
Technical Field
The present invention relates to the field of optical imaging technology, and in particular, to an optical system, a lens module, and an electronic device.
Background
With the development of science and technology and the popularization of intelligent electronic devices such as smart phones, devices with diversified camera shooting functions are widely favored by people, especially in the aspect of wide-angle camera shooting. At present, the wide angle is a common wide angle smaller than 84 degrees, the size of the shot object space is greatly different from the visual angle of human eyes, and the daily use of the shot object space is limited in the scene. The size of the object space which can be accommodated under the shooting condition with limited distance is about 1.6 times of the original 84 degrees, and the coverage scene used daily can be more due to the addition of high pixels and high image quality. In addition, the wide-angle lens with large imaging area can allow more picture cutting in the process of shooting, and better video shooting stability is obtained. Therefore, a wide-angle lens with higher image quality is required to meet the development trend of high-pixel ultra-thin optical lens assembly.

In one embodiment, the optical system satisfies the condition that the FOV is 101.0 less than or equal to 105.0, wherein the FOV is the maximum field angle of the optical system. The maximum field of view FOV is greater than 90 ° and can cover more scenes.
In one embodiment, the optical system satisfies the conditional expression of 1.10< TTL/ImgH <1.45, wherein TTL is the distance from the object side surface of the first lens to the imaging surface on the optical axis, and ImgH is half of the diagonal length of the effective imaging area on the imaging surface. ImgH determines the size of the electronic photosensitive chip, and the larger ImgH, the larger the maximum electronic photosensitive chip size that can be supported, the higher the pixel support. The reduction of TTL makes the whole optical system length compressed, and makes it easy to realize ultra-thin and miniaturized. The optical system can support the high-pixel electronic photosensitive chip, meanwhile, the length of the optical system is compressed, and the optical system with small size accommodates the large-size photosensitive chip.

The reasonable back focal length ensures the matching property of the lens group and the electronic photosensitive chip, and the combination of positive and negative refractive power of the front three lenses (the first lens, the second lens and the third lens) realizes better achromatic effect and spherical effect. The lens has the advantages that the thicknesses of the first lens, the second lens and the third lens on the optical axis can be kept appropriate, the structural compactness of the lens is effectively improved, the length of an optical system can be reduced, and the lens is beneficial to molding and assembling.

The aspherical sagittal change of the fifth lens and the sixth lens is favorable for correcting the aberration generated by the optical system under a large field angle and improving the image quality, and on the other hand, the aspherical matching of the lenses reduces the light deflection angle and is favorable for reducing the sensitivity. The reasonable control of the thickness of the middle part (the thickness on the optical axis) and the thickness of the side part (the thickness on the circumference) can reduce the whole length and the molding risk of the optical system.
In one embodiment, the optical system satisfies the conditional expression (f3+|f4|)/(r31+|r41|) <12.00;
