As an  Optical Domes Supplier , share with you. The first method: grinding is to remove the uneven bubbles and impurities on the surface of the optical lens, (about 0.05-0.08) to play a molding role. The second process is to eliminate the damaged layer of the polished optical lens and fix the R value. The third method is the polishing process, that is, polishing the optical lens in a single polishing process. This process is mainly to make the appearance better. The fourth method is to clean the polished lens to clean the polishing powder on the surface to prevent clogging. The fifth method is to grind the outer diameter of the original optical lens to the specified outer diameter. The sixth method is coating. It will require coating the surface of the coated lens with one or more colored films or other films. The seventh method is to apply ink, which will require an optical lens to prevent a layer of black ink from being reflected on the outer edge of the map. The eig

Drones have been widely used in military, civilian and commercial applications. By carrying a variety of sensors (including multi-spectral, lidar, photogrammetric ,  thermal energy  and other  sensing devices) and cameras,  the drone  can be used for weather, agriculture, geography  and other aspects to get  information. As a manufacturer of optical components, we will  talk to you about  the optical components used in the aerial photography of drones. At the same time, C LZ  Precision Optical Instrument Co., Ltd. provides you with optical components that can be used in drones, such as optical lenses, optical windows, optical prisms, optical reflectors, optical domes   and other optical components. In order to meet the observation requirements of small drones  for  large-field optical imaging, a design of a   micro-miniature camera  with bionic  compound-eye  for  large-field   has emerged. The sub-lens of this camera adopts  the combination of  cemented double len s  to reduce syst

As a  Fused Silica Windows Manufacturer , share with you. Among one of the most usual optical product concerns is the difference in between merged silica as well as integrated quartz. From a production perspective, integrated quartz is made by the melting of highly pure, smashed all-natural quartz. On the other hand, merged silica is made by thawing very pure silica through a fire hydrolysis procedure where it oxidizes as well as creates an amorphous (crystal-free) framework. Both products share all the above described homes with the exemption that quartz, due to metallic impurities in the smashed forerunner product, does not transmit well in the ultraviolet range. Fused Silica Mirrors Connected to the tool belt of every optical developer is an astonishing variety of products from which to pick. Nonetheless, from low and high index optical glasses, absorbent filters, different crystals, compounds and also plastics, very few can boast the variety charm of integrated silica. In

As an  Optical Windows Supplier , 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 determination of the quality of optical glass also includes some special and stricter indicators. Optical Glass Lenses Today we will talk about the importance of optical glass having a high degree of transparency. The brightness of the imaging 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 at the interface reflection of the optical parts and the other part is absorbed by the medium (glass) itself. The former increases with the refractive index of the glass. This value is very large for high refractive index glass, such as about 6%
