Problems solved by technology
[0003] The lens in the optical lens can change the optical characteristics of the optical system by changing its shape and refractive index, but in the process of lens optimization, the surface shape of the lens often changes greatly, which makes the lens difficult to process or the processing tolerance is too large It does not meet the requirements, and it is easy to generate stray light during the processing, which will lead to the deterioration of the photographic effect of the optical lens

Abstract
The disclosure relates to a lens group for optical lens and an optical lens. The lens group comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, which aresequentially and coaxially arranged from the object side to the image side along the optical axis of the optical lens; the fourth lens is a negative lens and the object side surface of the fourth lens is a concave surface, wherein the object side surface and the image side surface are aspheric surfaces, and the surface sagittal vector is not greater than 0.3 mm; the fifth lens is a positive lensand the image side surface of the fifth lens is a convex surface, wherein the object side surface and the image side surface of the fifth lens are aspheric surfaces, and the surface sagittal vector isnot greater than 0.4 mm; the sixth lens is a negative lens, wherein the object side surface of the sixth lens is aspheric, the image side surface of the sixth lens is concave and aspheric, the imageside surface of the sixth lens is provided with at least one inflection point, and the surface sagittal of the object side surface and the image side surface of the sixth lens is not larger than 0.5 mm. According to the technical scheme, the lens in the lens group for the optical lens is convenient to process.
Description
technical field [0001] The present disclosure relates to the technical field of imaging lenses, and in particular, relates to a lens group for an optical lens and an optical lens. Background technique [0002] With the rapid development of smart phone technology, the functions of mobile phones are not limited to traditional communication, and its camera function has also been widely used. Therefore, people's requirements for optical lenses are also constantly improving. High resolution, low aberration, volume Optical lenses that are small and lightweight tend to be more attractive to consumers. [0003] The lens in the optical lens can change the optical characteristics of the optical system by changing its shape and refractive index, but in the process of lens optimization, the surface shape of the lens often changes greatly, which makes the lens difficult to process or the processing tolerance is too large It does not meet the requirements, and it is easy to generate stra...
