Embodiment approach 1

[0036] as attached figure 1 As shown, the present application provides an optical lens assembly. The optical lens assembly includes a first lens L1 with a positive refraction force, a second lens L2 with a negative refraction force, and a negative refraction lens L2 from the object side to the image side. The third lens L3 with positive bending force, the fourth lens L4 with positive bending force, the fifth lens L5 with positive bending force, the sixth lens L6 with negative bending force, the seventh lens L7 with positive bending force, and negative bending force Force's eighth lens L8. An infrared filter IR and an imaging surface of an image sensor S are both arranged on the image side of the optical lens assembly. In this embodiment, the infrared filter IR is arranged between the eighth lens L8 and the imaging surface, and the infrared filter IR filters the light passing through the optical lens assembly to a specific wavelength band, such as filtering out the near-infrar...

Description

technical field [0001] The present application relates to an optical lens technology, and more specifically, relates to an optical lens assembly composed of eight lenses. Background technique [0002] At this stage, with the rapid development of technology and the continuous improvement of semiconductor process technology, high-quality optical lens components have gradually become the mainstream trend of the market. With the ever-changing specifications of electronic products, the optical lens components mounted on them are also becoming more diversified, not only pursuing thinness and good imaging quality, but also pursuing designs with larger apertures and field of view. The existing optical lens components are thick and heavy, and the design of the aperture value and the angle of view cannot meet the market demand. [0003] In order to meet higher imaging quality and bring better imaging experience to users, more lenses are needed to achieve it, and lenses with more lens...
