          Quartz glass is an excellent glass material - hai an Ming guang optical technology co. LTD

          2020/4/30      view:
          Quartz glass is an important new material in modern science. Quartz glass provides a large number of key materials for high - level fields such as electric light source, electron, laser and aerospace. Quartz glass is the glass material. Quartz glass has good characteristics, quartz glass is composed of pure silica, quartz glass is a high-purity material for the electronics industry, the production of silicon single crystal crucible, integrated circuit manufacturing used for the diffusion of the tube and instruments are made with quartz glass; The expansion coefficient of fused quartz glass powder is small and the strength is large. The spectral loss of quartz glass, the leading material in the manufacture of optical fiber.
          Haian mingguang optical technology co., LTD. The main production of various specifications of color optical glass and colorless optical glass, color filter, filter, filter, heat insulation glass, quartz glass, through infrared, near infrared, ultraviolet, glass, uv black glass, neutral grey, orange, green, yellow glass, bandpass filter, special filter paper and other optoelectronic equipment products. Telephone hotline: 18851381500! Welcome!
          Optical glass needs an accurate index of refraction, abbe number and high transparency and uniformity. Optical glass is mixed with oxides of silicon, boron, sodium, potassium, zinc, magnesium, calcium and barium according to a specific formula. It is melted at high temperature in a platinum crucible and stirred evenly with ultrasonic wave to remove bubbles. The glass is then cooled slowly for a long time to avoid internal stress. After cooling, glass blocks need to be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks were heated, forged and pressed to form optical lens embryos.
