For wavelength calibration, Avantes offers a variety of sources including Argon, Mercury-Argon, Neon, Zinc, and Cadmium. All Avantes spectrometers are factory wavelength calibrated and do not require recalibration as they have fixed slits and optics. For those customers who wish to do their own calibrations, the AvaLight-CAL light sources can be used for recalibration purposes. For auto-calibration, AvaSoft-Fill provides a calibration procedure to make this easy.
The AvaLight-CAL-xxx is a spectral calibration lamp, available in Mercury-Argon (253.6-922.5 nm), Neon (337-1084.5 nm), Argon (696.5-1704 nm) Zinc (202.5-636.2 nm), and Cadmium (214.4-643.8 nm) versions. The major lines including their relative intensity and structures are shown below.
The standard SMA-905 connector supplies an easy connection between the lamp and optical fibres, making the AvaLight-CAL-xxx a low-cost wavelength calibration system for any fibre-optic spectrometer. AvaSoft-Full spectroscopy software includes an automatic recalibration procedure.
The AvaLight-CAL-Mini, AvaLight-CAL-AR-Mini, AvaLight-CAL-Neon-Mini all come in the Mini-housing and are equipped with a connector at the rear enabling to switch the unit on/off remotely with a TTL signal.
The AvaLight-CAL can also be delivered in rack-mountable version, to be integrated into Avantes 19” Rack-mount or the 9.5” desktop housing. The PS-12V/2.08A power supply should be ordered separately.

Calibrating your spectrometer has never been easier: the AvaLight-HAL-CAL-Mini and Avalight-DH-CAL are NIST(National Institute of Standards and Technology)-traceable, calibrated light sources used to measure absolute spectral intensity.
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.
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 USB 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 across 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 into 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.
