Problems solved by technology

[0003] The 3-4 lens types commonly used in mobile devices, such as mobile phones, tablet computers, and other wearable electronic devices, such as US 7,564,635 and US 7,920,340, cannot present a more detailed image quality; while the five-element lens Smaller lenses may have better image quality. However, when the aperture is large, such as US 8,605,368, US8,649,113, and Taiwan application numbers 102137030 and 102121155, it is often accompanied by sensitivity problems in manufacturing and assembly, making mass production difficult. Increase the cost of mass production
Or in order to reduce the assembly tolerance, the surrounding imaging quality has to be sacrificed, making the surrounding imaging blurred or deformed

Description

technical field [0001] The invention relates to an optical lens, in particular to a miniaturized five-piece optical imaging lens applied to electronic products. Background technique [0002] High-quality small photographic lenses are standard equipment for various mobile devices, and with the progress of semiconductor manufacturing, the pixel area on the electronic photosensitive component is getting smaller and smaller, which in turn requires more fine-grained resolution of the camera lens power, so that more detailed picture quality can be presented. [0003] The 3-4 lens types commonly used in mobile devices, such as mobile phones, tablet computers, and other wearable electronic devices, such as US 7,564,635 and US 7,920,340, cannot present a more detailed image quality; while the five-element lens Smaller lenses may have better image quality. However, when the aperture is large, such as US 8,605,368, US8,649,113, and Taiwan application numbers 102137030 and 102121155, i...
