                                            Optical lens product classification


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 with a plastic lens or a glass lens assembled 

with a glass lens, the structure is composed of a plurality of lenses. In general, the greater the number of lenses, the higher 

the image quality of the lens. Plastic lenses and glass lenses have great differences in material properties, processing techniques, 

and light transmittance, so the final application range is also very different. 

The 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 

is convenient for miniaturization. It is widely used in mobile phones, digital cameras and other equipment. The glass lens is made up of glass lenses. 

Due to its high requirements on molding technology, coating process and precision processing, and its high light transmittance, it is more used in 

high-end imaging fields, such as SLR cameras and high-end lenses. Scanners and other equipment. The glass-plastic hybrid lens is composed of a 

part of glass lens and a part of plastic lens. It combines the characteristics of both, has high refractive index optical performance and stability, 

and is widely used in lens modules such as surveillance cameras, digital cameras, and car cameras.
