Optical lens is generally called camera lens or photographic lens, lens for short, its function is optical imaging. The optical lens is made of optical lens, which is a component in the optical imaging system, which directly affects the quality of the image and the realization and effect of the algorithm.

With the camera, we will use the camera lens. The camera lens is very important to the camera. Without the lens, the camera loses its function. The quality of the camera lens directly affects the quality of shooting.

From the perspective of the optical lens characteristics of the lens, optical lenses are mainly divided into three categories: plastic lenses, glass lenses and glass-plastic hybrid lenses. Whether it is a plastic lens composed of plastic lenses or a glass lens composed of glass lenses, the structure is composed of multiple lenses. Generally speaking, the more the number of lenses, the higher the imaging quality of the lens.

Plastic lens is a lens composed of optical plastic lens. Due to its strong plasticity, it is easy to be made into aspherical shape and is convenient for miniaturization. It is widely used in mobile phones, digital cameras and other equipment. The glass lens is composed of glass lenses. Because of the high requirements on molding technology, coating technology, processing, etc. and its high light transmittance, it is more used in the imaging field, such as SLR cameras, scanners, etc. equipment. Glass-plastic hybrid lens, which is composed of part of glass lens and part of plastic lens, combines the characteristics of the two, has high refractive index optical performance and stability, and is widely used in lens modules such as surveillance cameras, digital cameras, car cameras, etc. .
