UV light output without IR heat

  • A bright UV light with desirable wavelength range
  • UV light with blocking IR heat
  • It is also possible to obtain a desirable UV wavelength range with
    the combination of a mirror module and optical filters.
    *If you would like to know about a combination of filters, please contact us.
