Optical lens refers to glass that can change the direction of light propagation and change the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass is defined as a glass that has specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance and light absorption, and has uniform optical properties. Optical glass is made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasonic waves to remove air bubbles; Cool down slowly over time to avoid internal stress on the glass block. After cooling, the glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged into optical lens blanks.

Components made of optical glass are key components in optical instruments. Optical glass can be used to manufacture optical lenses such as lenses, prisms, mirrors and windows in optical self-percussion crushing equipment. Optical lenses are lenses made of optical glass. During the inspection and installation of optical lenses, care must be taken to avoid damage and contamination of the lenses. At the same time, after a new lens is installed, it should be cleaned regularly. The process is fairly simple and, if done correctly, will extend the life of the lens and reduce costs. On the contrary, it will reduce the service life. 
For many industries, optical lenses are one of the indispensable and important products. If there are no optical lenses, many jobs will be seriously delayed. It is precisely because of this reason that today's optical lens market is better. Development, this is an opportunity for many optical lens manufacturers to gain more market space.
