Spectrometer wavelength calibration sources are available for convenient, reliable spectrometer calibration across UV-NIR wavelengths.

Options include mercury-argon (253-1700 nm), krypton (427-893 nm), neon (540-754 nm), argon (696-1704 nm) and xenon (916-1984 nm) gas-discharge emission sources. With multiple wavelength options and emission lines to utilize, users can more readily choose a source, or combination of sources, to match analytical wavelengths of interest within the measurement range.

Quick tip: If you a few more budget resources to put to good use, our wavelength calibration sources are a great investment. What's more, they're conveniently available for purchase online.



  • Gas-discharge sources — produce atomic emission lines for performing reliable spectrometer wavelength calibration
  • UV-NIR coverage — choose from multiple sources across a broad range of wavelengths
  • Remote on/off operation -- helps you avoid disturbing experiment setups
