  As a   Fused Silica Windows Manufacturer , share with you. (1) This operation process is suitable for silica sol, the surface layer or transition layer of the shell. (2) The silica sol used in this process is the same as the zircon powder coating, which is 30% silica. (3) The wetting agent and defoaming agent in this process operation are the same as zircon powder coating. (4) The flow cup viscometer used in this operation is Zahn cup and the outlet aperture is Φ5.28mm. (5) Coating preparation: Fused Silica Windows 1. The preparation of fused silica powder, 320 mesh (network number: 0.044) 275 mesh (network number: 0.052) 200 mesh (network number: 0.076) 120 mesh (network number: 0.125) The mass fraction of SiO2 in the fused silica powder is 99.5% or more. Among them: 320 mesh accounts for 50%, 200 mesh accounts for 25%, and 120 mesh accounts for 25%. The percentage is calculated as the mass fraction, that is, the weight ratio. 2. The viscosity of the paint is 50~60 seconds, strictly

  Among infrared lasers, 1064nm Nd: YAG lasers are widely used in various high-tech fields. YAG is currently the laser crystal, which matrix with the most excellent comprehensive characteristics. After being doped with neodymium (Nd), it outputs 1064nm of light. The maximum continuous output power reaches 1000w. After improvement, LD (laser diode) pumping is often used to improve the efficiency of the laser and meets the application requirements of high efficiency, high power and long service life of the laser. Optical engineers use different resonant cavities according to different laser applications, including two-mirror ring cavity, triangular ring cavity, four-mirror 8-shaped ring cavity, six-mirror double-end pumped ring cavity, etc. Different resonant cavities use different optical components, including bi-convex lenses, coupling lenses, anti-reflection mirrors, high reflection mirrors and half-waveplates. Two-mirror ring cavity In order to adjust the parallelism of the laser bea

  As a   Dome Lens Manufacturer , share it with everyone. The small details that should be paid attention to in the ordinary use of optical glass filters: Optical Glass Lense 1. Take care as much as possible during normal use, and pay attention to the external environment to prevent the filter from being scratched. 2. Wear finger cots when touching the filter to avoid corrosion of the substrate surface by salt and acid on your hands. 3. When taking the filter, hold the edge of the filter in your hand, even if you are wearing a finger cot, do not touch the transparent surface of the filter. 4. The filter should be placed on a soft and clean object, not on glass, metal, table, or dirty paper. 5. When storing, it should be wrapped in clean capacitor paper or special lens cleaning paper. The storage temperature is around 23℃, and the humidity is not higher than 40%. It is better to put it in a dry storage cabinet. 6. Clean it immediately when you find stains on the surface. Because dust ca

  Fused Silica Mirrors As   Fused Silica Precision Lenses Supplier  will briefly introduce the performance difference between quartz and glass, and explain their respective characteristics. The difference between ordinary glass and quartz Quartz glass  is a special industrial technical glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as: 1. High temperature resistance. The softening point of quartz glass is about 1730 ℃, which can be used for a long time at 1100 ℃, and the temperature can reach 1450 ℃ in a short time. 2. Corrosion resistance. Except for hydrofluoric acid, quartz glass hardly chemically reacts with other acids. Its acid corrosion resistance is 30 times better than acid resistant ceramics and 150 times better than stainless steel, especially chemically stable at high temperatures. Sex is unmatched by any other engineering materials. 3. Good thermal stability. The thermal expansion coe

  As a   Dome Lens Manufacturer , share it with everyone. Optical glass can change the direction of light propagation. Optical glass is widely used in many modern high-tech industries such as aerospace, information, microelectronics, surveying and mapping with its unique characteristics of high temperature resistance, low expansion coefficient, high mechanical strength, and good chemical properties. Optical glass is widely used in lenses and prisms of optical instruments. Optical glass must meet the requirements of light imaging, so the quality of optical glass is also very high. Glass Optical Domes The qualified optical glass must meet the following requirements: 1. The optical constants of the optical glass and the same batch of glass must be the same. The optical glass has a prescribed standard refractive index value for light of different wavelengths, which is the basis for the optical designer to design the optical system. Therefore, the optical constants of the optical glass prod
