AR-1

The AR-1 Calibration Source is a spectral wavelength calibration source specifically designed for NIR spectrometers like our NIR256 and NIR512 models. The AR-1 produces low-pressure argon emission lines from 696-1704 nm for use in performing fast, reliable spectrometer wavelength calibrations. The spectral emission lines are printed on the lamp's housing.

 

 

Our spectrometers are carefully calibrated as part of our standard quality assurance process. However, as is the case with all spectrometers, wavelength will drift slightly due to time and environmental conditions. With the AR-1, you can recalibrate your spectrometer using a spreadsheet program such as Microsoft Excel or a calculator that performs third-order polynomial regressions.

If wavelength accuracy is an important part of your work, consider including calibration spectra with every experiment.

The AR-1 operates with a 12 VDC power supply (included) or a 9V battery (not included) for field use. The AR-1 features an SMA 905 connector for interfacing to optical fiber assemblies.
