As an   Optical Domes Supplier , let me share with you. Optical glass is the foundation and important part of the optoelectronic technology industry, and its components are key components in optical instruments. Optical glass in a narrow sense refers to colorless optical glass. Optical glass lens molding technology is a high-precision optical component processing technology. It puts the softened glass into a high-precision mold, and under the condition of heating, pressure and oxygen-free, it can be directly molded at one time to achieve use. Required optical parts. This technology has now become one of the internationally advanced manufacturing methods for optical parts. Glass Optical Domes The optical glass molding method for manufacturing optical parts has the following advantages: 1. Without the need for traditional rough grinding, fine grinding, polishing, edging centering and other processes, the parts can achieve higher dimensional accuracy, surface accuracy and surface roug...

Visibility meter is an important tool for measuring the degree of haze in the atmosphere. Visibility depends on the interaction between infrared radiation and particles in the atmosphere. The visibility meter is based on the principles of light intensity attenuation and scattering. It determines the visibility of the day by measuring the extinction coefficient of the atmosphere. The  optical components  used in the visibility meter include bandpass filters and convex lenses. After the light passes through the optical lens and the optical filter, the relationship between the optical signal and the total radiation is calculated by the detector, and the visibility value is obtained. The commen  optical lens  is a quartz lens coated with an anti-reflection coating. The quartz lens narrows the divergence angle of the incident beam and increases the energy volume density of the beam. An anti-reflection film reduces the energy loss of transmitted light, thereby increasing t...

As a   Dome Lens Manufacturer , share with you. The difference between optical glass and other glasses is that as an integral part of the optical system, it must meet the requirements of optical imaging. Therefore, the judgment of the quality of optical glass also includes some special and stricter indicators. Optical Glass Lense Today we will talk about the importance of optical glass that must have a high degree of transparency. The image brightness of the optical system is proportional to the transparency of the glass. The transparency of optical glass to light of a certain wavelength is expressed by the light absorption coefficient Kλ. After the light passes through a series of prisms and lenses, part of its energy is lost by the interface reflection of the optical parts and the other part is absorbed by the medium (glass) itself. The former increases with the increase of the refractive index of the glass. For high-refractive-index glass, this value is very large. For example, ...

Is it necessary to install an optical lens for the high beam? Why is it necessary to install an optical lens for the high beam? What is the function? I believe that many people do not understand this problem. The function of optical lenses can be enlarged or reduced. The main purpose of installing optical lenses in automotive led headlights is to prevent the light source from scattering and improve the lighting of automotive headlights. Next,   Dome lens Manufacturer   wants to learn more about the pros and cons of the high beam lens. Optical Glass Lense Is it necessary to install an optical lens for the high beam? What are the benefits? The benefits of installing an optical lens for LED lights The LED car headlights need to be equipped with optical lenses to achieve the effect of condensing light. The light output brightness will not drop during use. The line-cutting star of the car light with a lens will not cause the headlight source to scatter and achieve a good condensing...

Infrared non-destructive testing technology is based on the principle of infrared radiation. This technology uses measurement and analysis of infrared radiation to diagnose and inspect tested samples, such as equipment or materials. The infrared detection system combines the photoelectric system. The system presents the measurement signal through the thermal image obtained by the infrared detection device. Infrared thermal imaging detection technology is fast, non-contact, full-field and non-destructive, which is widely used in aerospace, machinery, industrial production and other fields. In order to achieve the ideal capabilities of detection and resolution, some detectors need to work at low temperatures. Therefore, some infrared detection systems use a refrigerator to cool the detectors. When the measured object is in a thermal equilibrium state, it is not easy to detect and analyze its internal conditions. At the moment, an external thermal excitation source is usually used to appl...

As a   Fused Silica Windows Manufacturer , share with you. Quartz glass is a single-component amorphous material of silicon dioxide. Its microstructure is a simple network composed of silicon dioxide tetrahedral structural units. Since the Si-O chemical bond energy is large and the structure is very tight, optical quartz Glass has the performance of DuTe, especially the optical performance of transparent quartz glass is very excellent, in the continuous wavelength range of ultraviolet to infrared radiation has excellent transmittance.
