Ocean Optics spectrometer wavelength calibration sources are now available in configurations that span the UV to the NIR, with more convenient battery options, remote on/off, and LED indicators for battery charge and lamp activation.

The newer wavelength calibration source series (-2 models) includes 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 more emission lines to utilize, maintaining optimum spectrometer performance – for example, correcting for spectrometer baseline drift and related phenomena inherent to all spectrometers — is simpler to achieve.

 

  • 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
  • Convenient operation — sources include 5 VDC power supply and embedded, rechargeable lithium ion battery

  • The emission lines from atomic lamps are the most reliable standards for spectrometer wavelength calibration. Resulting from atomic level transitions, these emission lines are intrinsic to the source and therefore are primary standards, requiring no calibration themselves.
  • Atomic emission is almost infinitely narrow; the position of the emission line can be accurate to 0.001 nm. Their high level of accuracy and reliability make wavelength calibration lamps ideal for procedures ranging from routine checks of instrument performance to total recalibration of a spectrometer.
  • Spectrometer wavelength recalibration is included with your purchase of an Ocean Care Service Plan.
  • Depending on your spectrometer configuration and calibration source, not all the emission lines may be evident. The emission line may fall outside the spectrometer range or its peak may be too narrow to detect with your setup.
