Product Details

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

Options include mercury-argon (253-923 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: For a modest investment, adding an Ocean Insight wavelength calibration source is the perfect complement for your spectrometer setup. What's more, they're conveniently available for purchase online.
