Optical lenses are mainly divided into three categories: plastic lenses, glass lenses and glass-plastic hybrid lenses.Whether it is a plastic lens assembled with a plastic lens or a glass lens assembled with a glass lens, its structure is composed of multiple lenses.Generally speaking, the more lenses there are, the higher the image quality of the lens.

Plastic lenses and glass lenses are very different in terms of material properties, processing technology, light transmittance, etc., so the final scope of application is also very different.Plastic lenses are lenses composed of optical plastic lenses. Due to their strong plasticity, they are easy to make aspheric shapes and convenient for miniaturization. They are widely used in mobile phones, digital cameras and other equipment.

Glass lenses are composed of glass lenses. Due to the high requirements for molding technology, coating technology, precision machining, etc., and its high light transmittance, they are more used in high-end imaging fields, such as SLR cameras, high-end scanners, car imaging systems, high-end security video surveillance and other equipment.

Glass-plastic hybrid lenses are composed of some glass lenses and some plastic lenses. They combine the characteristics of the two and have high refractive index optical properties and stability. They are widely used in lens modules such as surveillance cameras, digital cameras, and car cameras.
