Optical glass production process and optical lens characteristics and uses


Quartz glass is a single-component amorphous material of silicon dioxide. Its microstructure is a simple network composed of silicon dioxide tetrahedral structural units. Due to the large chemical bond energy of Si-O, the structure is very tight. Therefore, optical quartz glass has unique properties, especially the optical properties of transparent quartz glass is very excellent, in the continuous wavelength range of ultraviolet to infrared radiation has excellent transmittance.

  Quartz glass has extremely low thermal expansion coefficient, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, The best UV-transmitting spectrum performance is based on optical lens and visible light and near-infrared spectrum performance, and has higher mechanical properties than ordinary glass.

  Do you know the production process of optical quartz glass? Let’s take a look at it together:

   1. Making a melting furnace: There are two types of melting furnaces: clay furnace and platinum furnace. In recent years, the optical glass that enters rare elements has used small platinum furnaces to maintain the stability of quality.

   2. Put the optical glass raw materials: the melting furnace (especially the clay furnace) is dried for a long time, and then put in the melting furnace according to the special formula and through the selection of other raw materials In, ready to melt.

   Three, heating, lens design melting, mixing: heating conditions, depending on the raw materials. However, various raw materials must be mixed evenly to achieve homogeneity.

   Four. Cooling: Long-term 'Xu Chill'. However, the length of time also varies with the raw materials, which is the most important process to ensure excellent quality.

   5. Split furnace, sorting: split the clay furnace, take out the massive rough embryo and sort it.

  6. Viewing, testing, and shaping: View or test its various functions one by one to ensure the excellent quality of quartz glass.

   Seven. Blocking, chamfering (trimming): Block the rough block into small pieces and chamfer the laser lens according to the usage and standards.

   8. Preform forming: After heating and softening the rough embryo, press the embryo to form according to the standards of the engineering drawing. However, it is necessary to make or prepare various molds, tools and auxiliary materials in advance.

  The qualified optical glass block is heated and forged to form an optical lens blank. Then, after each process of production, processing and testing, a qualified optical lens is finally formed. Optical Lenses Medium and high-precision optical lenses are suitable for laser stage lights, cameras, fisheye lenses, projectors, telescopes, fingerprint readers, microscopes, digital cameras, etc. Ordinary optical lenses are suitable for magnifying glass, stage lighting, high-power laser mirror kits, craft gifts, sight glasses (door mirrors), etc.

  The optical lens includes a convex lens for condensing and parallel light, a concave lens for light diffusion and wide-angle, a cylindrical lens that emits a line spectrum using only one side of transmission, and Optical fiber or ultra-small unit spherical lens, hemispherical lens, achromatic lens formed by bonding two lenses with functions such as eliminating chromatic aberration and spherical aberration, etc. Application requirements in a wide range of fields such as imaging.

   For many industries, optical lenses are one of the indispensable and important products. Without optical lenses, mirrors will cause serious delays in many tasks. Because of this reason, the optical lens market can develop better today, but for related manufacturers, it will also face more cruel challenges. But it has to be said that at the same time as the challenge comes, it may not be an opportunity. For many optical lens manufacturers, the opportunity to gain more market space is close at hand.

  Optical lens products come in a variety of shapes and materials, which can be combined optimally according to specific applications. According to customers' special requirements for the outer diameter or appearance shape of optical lenses, we provide short-term low-cost processing services.
