NIST Traceable Calibrated Halogen Light Source
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.
The AvaLight-HAL-CAL-Mini is a compact, affordable light source, and is calibrated for the visible range (350-1095nm). As an option, an extended calibration for the near infrared spectral range (1100-2500nm) 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 is simple a straight forward 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 both include a power supply.
Visible and optional NIR range
For radiance calibration in the visible spectral range (360-1100nm), we offers the AvaSphere-50-LS-HAL-CAL.
This radiance calibration sphere is normally used to calibrate a spectrometer and a bare fibre with an SMA connector. This uniform source ensures that the fibre is homogeneously illuminated during calibration.
The AvaSphere-LS-HAL-CAL is supplied with a power supply and a CD-ROM with the calibration file in ASCII format.
For homogeneous illuminated areas
For calibrations in the ultraviolet and visible range (200-1099nm), the AvaLight-DH-CAL is the best solution.
This source can be used with all AvaSpec spectrometers to calibrate for absolute spectral intensity, and is supplied with a built in diffuser (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 (200-1099nm) and one over the visible and near infrared range (350-1099nm). 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 200-1100nm range, we offer the AvaLight-DH-BAL-CAL.
For ultraviolet range calibration only (200-400nm), the AvaLight-D-CAL is the best choice.
The calibration files can be imported in the AvaSoft-IRRAD application software, for intensity calibration which converts your spectrometer into a spectroradiometer.
The AvaLight-DH-CAL-ISP-xx is a special version of these calibrated light sources, designed to facilitate coupling of the AvaSphere-xx-IRRAD integrating spheres to the light source (xx is 30, 50 or 80mm - internal sphere diameter).
The AvaLight-DH-CAL, AvaLight-DH-BAL-CAL and AvaLight-D-BAL-CAL all include a power supply.
