Product Details


The AR-1 Calibration Source is a primary wavelength calibration standard specifically designed for near-IR spectrometers like our NIRQuest family. The AR-1 produces low-pressure argon emission lines from 696-1704 nm for use in performing fast, reliable spectrometer wavelength calibrations. Easily identifiable emission lines are printed on the lamp’s housing.

The AR-1 can be used to verify the wavelength accuracy of any spectrometer and can also be used to recalibrate Ocean Optics spectrometers, if necessary.

The AR-1 operates with a 12 VDC power supply (included with the unit) or 9V battery (not included). Use any SMA fiber optic cable to connect with the AR-1.

  • Primary standard requires no calibration or verification with strong lines in the near-IR
  • Easy-to-use with calibration lines printed on the lamp housing
  • Portable with 9V battery optional for power supply

Included with the Product:

  • 12 VDC Power Supply
