Abstract
The invention provides an optical lens and electronic equipment employing the same. The optical lens comprises a lens cone which at least comprises two parts with different internal diameters. There is a step-shaped segment different layer between the internal walls of different parts of the lens cone. The optical lens also comprises at least two lenses disposed in the lens cone. Each lens comprises an optical part and a non-optical part. The step-shaped segment different layer is located between the two adjacent lenses which are respectively located at different parts of the lens cone. Moreover, the external diameter of each lens is matched with the internal diameter of the corresponding part of the lens cone. Because the step-shaped segment different layer is located between two adjacent lenses, the step-shaped segment different layer can withstand the pressure on the lens loaded in the lens cone from the lens which is subsequently loaded in the lens cone, thereby solving a problem of poor imaging quality caused by the compressive deformation of the lenses.
Description
technical field [0001] The invention relates to the technical field of imaging equipment, and more specifically, to an optical lens and electronic equipment using the optical lens. Background technique [0002] At present, electronic devices such as smart phones and digital cameras have become the main tools for people to take pictures. With the upgrading of electronic products, people have higher and higher requirements for the imaging quality of electronic products. [0003] Existing optical lenses are all stacked structures that use a lens barrel as a carrier to carry various optical components, wherein the optical components include one or more lenses. However, when the lenses are sequentially loaded into the lens barrel from the object side to the image side, the subsequent loaded lenses will exert pressure on the lenses already loaded in the lens barrel towards the object side, which will cause the lenses in the lens barrel to be deformed under pressure. , which in t...
