UV-VIS optical fiber
ST365-35

Usable borosilicate glass fiber for UV light (365nm)

  • Much more flexible than Silica fibers
  • Finer randomization with smaller diameter
  • Transmits much light with wider NA

Application

  • UV-curing
  • Penetrant testing
  • Detecting flux residue and leak
  • Fluorescence, Light-storing reactions
  • Anti-counterfeit etc.
