AvaLight-HAL-CAL-Mini and DH-CAL Calibrated Light Sources


Calibrating your spectrometer has never been easier: the AvaLight-HAL-CAL-Mini and Avalight-DH-CAL are NIST traceable, calibrated light sources to measure absolute spectral intensity with.

The AvaLight-HAL-CAL-Mini is a compact, affordable light source. It is calibrated for the visible range (350-1095 nm). Optionally, an extended calibration for the near-infrared spectral range (1100 - 2500 nm) can be ordered. It has a built-in diffuser, a cosine corrector with SMA adapter and comes with a calibration file in ASCII format. Calibration can be done using the AvaSoft software.

The AvaLight-HAL-CAL-ISPxx-Mini is a special version of the Avalight-HAL-CAL-Mini, which enables coupling any of Avantes’ AvaSphere-xx-IRRAD integrating spheres to the lightsource (xx = 30, 50 or 80) for calibration. This source is supplied with a special bottom plate to stabilize the AvaSphere. The Avalight-HAL-CAL-Mini and Avalight-HAL-CAL-ISPxx-Mini include a power supply.

  • Visible and optional NIR range
  • Built-in diffuser
  • Versatile



For calibrations in the ultraviolet and visible range (200 - 1099 nm), the AvaLight-DH-CAL is the best solution. This source can be used with all AvaSpec spectrometers to calibrate for absolute spectral intensity. It is supplied with a built-in diffuser, a cosine corrector (CC-VIS/NIR) with SMA adapter and a CD-ROM containing the calibration files in ASCII format.

Two calibration files are included: one for irradiance calibration over the full range (200 - 1099 nm) and one over the visible and near infrared range (350 - 1099 nm). For the first file, both the deuterium and the halogen bulb should be used during calibration. The second file is to be used with only the halogen light. The halogen-only spectrum provides a smoother black-body calibration spectrum for the longer wavelengths.

For a more balanced spectrum accross the 200 to 1100 nm range, Avantes offers the AvaLight-DH-BAL-CAL. For ultraviolet range calibration only (200-400 nm), the AvaLight-D-CAL is the right choice.

The calibration files can be imported in the AvaSoft-IRRAD application software, for intensity calibration which turns your spectrometer into a spectroradiometer.

The AvaLight-DH-CAL-ISPxx is a special version of these calibrated light sources, meant to facilitate coupling of the AvaSphere-xx-IRRAD integrating spheres to the light source. (xx is 30, 50 or 80). The AvaLight-DH-CAL, AvaLight-DH-BAL-CAL and AvaLight-D-BAL-CAL all include a power supply.

  • Built-in diffuser and cosine corrector
