Deuterium light sources

Deuterium lamps provide the lowest wavelength output. A stable molecular deuterium discharge emits radiation through the UV, while VIS and IR are negligible. The silica windows or bulb material transmits above 160 or 190 nm.

Deuterium lamps are extensively used in UV spectrophotometry and as spectral irradiance standards for the UV.

  • Continuous UV spectrum 160 – 400 nm
  • UV source with low VIS and IR output
  • Preferred source for UV spectroscopy
