What are the advantages of optical glass lens application in industrial field?

Optical glass lenses have the following advantages in the industrial field:

First, the optical performance

High light transmittance

Optical glass lenses have high light transmittance, which allows most of the light to pass through the lenses. For example, in some high-precision optical instruments, such as microscopes and telescopes, the light transmittance can reach more than 90%. This makes the energy loss less when the light propagates in the lens, and can ensure a clear and bright imaging effect. In industrial testing equipment, lenses with high light transmittance can allow operators to observe the details of the tested object more accurately and improve the accuracy of testing.

Accurate refractive index control

The refractive index of optical glass lens can be accurately controlled. Different industrial application scenarios have different requirements for refractive index. For example, in an optical imaging system, aberration can be effectively corrected by selecting lenses with appropriate refractive index. By combining lenses with different refractive indexes, an achromatic lens group can be designed, so that the imaging can be kept clear and accurate under different wavelengths of light. This characteristic of precisely controlling the refractive index is very important in high-precision optical equipment such as mask aligner, which can ensure the lithography accuracy in the chip manufacturing process.

Second, the physical performance.

High hardness and wear resistance

Optical glass lenses have higher hardness, which can better resist scratches and wear compared with some plastic lenses. In industrial environment, such as machine vision system, lenses may be rubbed by dust, particles and so on. The high hardness of optical glass lens enables it to maintain good optical surface quality during long-term use and reduce the degradation of imaging quality caused by surface scratches. For example, in the automatic production line inspection system of automobile industry, optical glass lenses can work stably for a long time without frequent replacement.

Good thermal stability

The optical and physical properties of optical glass lenses are relatively stable when the temperature changes. In some high-temperature industrial environments, such as the monitoring system of iron and steel smelting factory or the observation window of high-temperature furnace, optical glass lenses can withstand high temperature without obvious deformation or deterioration of optical performance. For example, some special optical glasses can work normally in a high temperature environment of several hundred degrees, and the changes of optical parameters such as refractive index are very small, thus ensuring the imaging and detection accuracy in a high temperature environment.

Third, the chemical properties

Good chemical stability

Optical glass lenses have good tolerance to most chemicals. In industrial production, you may be exposed to various chemical reagents, gases, etc. For example, in the monitoring equipment of chemical production, optical glass lenses can resist the corrosion of chemicals such as acid and alkali, and their optical properties will not be affected by chemical corrosion. This enables it to work reliably in the complex chemical industry environment and prolongs the service life of the lens.

Four, accuracy and machinability

High precision manufacturing

Optical glass lenses can achieve high surface accuracy and surface smoothness through precision grinding, polishing and other processing technologies. In the industrial fields such as optical mold manufacturing and optical lens assembly, this high-precision lens can meet the strict assembly requirements. For example, when manufacturing high-end camera lenses, the surface accuracy of the lenses can reach micron or even nanometer level, which ensures that the imaging quality of the lenses meets the requirements of professional level.

Can be processed into complex shapes.

Optical glass lenses can be processed into various complex shapes according to industrial needs, such as aspherical lenses and free-form lenses. In laser processing equipment, aspheric optical glass lens can effectively focus and shape the laser beam, and improve the accuracy and efficiency of laser processing. These lenses with complex shapes can also be used for miniaturization and high-performance design of optical systems, and meet the increasing performance requirements of optical equipment in industrial fields.
