AvaLight-DH-CAL Calibrated Light Sources

Product information "AvaLight-DH-CAL Calibrated Light Sources"

200-1099 nm; Calibration Repeatability ±1.0%; Calibration Relative Uncertainty ±9%-±10%; Bulb Output 5, 80 µW cm-2 nm-1; Power Supply 100-240 VAC

Calibrating your spectrometer has never been easier: Avantes’ AvaLight-DH-CAL series are NIST-traceable, calibrated light sources to measure absolute spectral intensity with.

For calibrations in the ultraviolet (UV) and visible (VIS) range (200 to 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 to 1099 nm) and one over the visible and near infrared range (350 to 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. The calibration files can be imported in the AvaSoft-IRRAD application software for intensity calibration, which turns your spectrometer into a spectroradiometer.

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

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 (xx is 30, 50 or 80) to the light source. The AvaLight-DH-CAL, AvaLight-DH-BAL-CAL and AvaLight-D-BAL-CAL all include a power supply.
