      Reflector

      Product category:Optical lens
      Product name:Reflector

      The company produces a variety of wavelength media, metal, metal reinforced mirror. Specific parameters are as follows.

      The gold plated mirror has a higher reflectivity and better chemical stability than the silver and aluminum in the infrared spectral region. After environmental testing, in the harsh environment can still maintain good optical properties. And has a good film firmness, infrared reflectance is greater than 98%. Our company's gold mirror, can ensure a good surface quality, so it is not easy to film, no pinhole characteristics.
      Material: class a BK7 optical glass, other optical glass
      Type: lambda /4@632.8nm
      Finish: III level
      Parallelism: <3'reflectivity: >98% in the infrared region
      Product size, parallelism and other indicators can be customized according to customer requirements.

      Protection of silver mirror, has a good film fastness, surface resistance is very good. After environmental testing, in the harsh environment can still maintain good optical properties. In the visible and infrared regions, there is a high reflectivity. Our protective silver mirror, can ensure a good surface quality, so that the film is not easy to remove, no pinhole characteristics.
      Material: class a BK7 optical glass, other optical glass
      Type: lambda /4@632.8nm
      Finish: III level
      Parallelism: <3'reflectivity: >95% in visible light
      Product size, parallelism and other indicators can be customized according to customer requirements.

      UV enhanced aluminum, with good UV band high reflectivity. The reflectivity can reach 80% at 200nm, and the average reflectivity can reach about in 200nm to 400nm. Suitable for measuring equipment such as spectrometer. Material: class a BK7 optical glass, other optical glass
      Type: lambda /4@632.8nm
      Finish: III level
      Reflectivity: >85% in visible light
      Product size, parallelism and other indicators can be customized according to customer requirements.
