Analysis of the knowledge points of optical lenses applied to cameras

        Optical lenses are generally called camera lenses or photographic lenses, referred to as lenses, and their function is optical imaging. Optical lens is made of optical lens, which is an essential component in the optical imaging system, which directly affects the quality of imaging and the realization and effect of the algorithm.

        When using a camera, we will use the camera lens. The camera lens is very important for the camera. Without the lens, the camera loses its function. The quality of the camera lens directly affects the quality of the shot.

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

        Plastic lens is a lens composed of optical plastic lenses. Due to its strong plasticity, it is easy to be made into an aspherical shape, and it is convenient for miniaturization. It is widely used in mobile phones, digital cameras and other equipment. Glass lenses are composed of glass lenses. Due to their high requirements on molding technology, coating technology, and precision machining, as well as their high light transmittance, they are more used in high-end imaging fields, such as SLR cameras, high-end Scanners and other equipment. The glass-plastic hybrid lens is composed of some glass lenses and some plastic lenses. It combines the characteristics of the two and has high refractive index optical performance and stability. It is widely used in surveillance cameras, digital cameras, car cameras and other lens modules. .
