AvaLight-HAL-CAL and DH-CAL Calibrated Light Source

AvaLight-HAL-CAL

The AvaLight-HAL-CAL is a compact, low-cost light source, calibrated for the VIS (350-1095nm). Optionally an extended calibration for the NIR spectral range (1100-2500 nm) can be ordered. This NIST traceable calibrated light source is developed for use with all AvaSpec spectrometers, to measure absolute spectral intensity.

The AvaLight-HAL-CAL comes with a built-in diffuser, a cosine corrector CC-VIS/NIR with SMA adapter and a CDROM with the calibration file in ASCII format. The AvaLight-HAL-CAL calibration file can be read by AvaSoft-IRRAD, a software package developed to turn your spectrometer system into a spectroradiometer.

A special version of the calibrated light source, the AvaLight-HAL-CAL-ISPXX, is available to couple the AvaSphere-XX-IRRAD integrating spheres to the light source (XX=30, 50, 80). This version comes with a special bottomplate to stabilize the Avaspheres.

The AvaLight-HAL-CAL cannot be used as an illumination source for spectral absorbance, transmission and reflection measurements. The AvaLight-HAL-CAL is calibrated together with the included PS-24V/1.25A power supply.

AvaSphere-50-LS-HAL-CAL

Specially for radiance calibrations in the VIS (360-1100nm) spectral range the AvaSphere-50-LS-HAL-CAL has been developed. Radiance calibrated systems normally include a spectrometer and a bare fiber with SMA connector and look at homogeneous illuminated areas. The AvaSphere-50-LS-HAL-CAL comes with a power supply and a CDROM with the calibration file in ASCII format.

AvaLight-DH-CAL

The AvaLight-DH-CAL is a calibrated light source for the UV/VIS/NIR spectral range (200-1099 nm). This NIST-traceable calibrated light source is developed for use with all AvaSpec spectrometers to measure absolute spectral intensity. The AvaLight-DH-CAL comes with a built-in diffuser, a cosine corrector CC-UV/VIS with SMA adapter and a CDROM with the calibration file in ASCII format. The software includes two calibration files, both valid for calibration with the cosine corrector. One calibration file can be used for irradiance calibration over the full range (200-1099 nm). In that case both the Deuterium and Halogen light need to be switched on during the calibration. The other calibration file can be used for irradiance calibration over the VIS/NIR range (350-1099 nm). In that case only the Halogen light needs to be switched on which gives a more smooth and stable output around 656 nm and at the higher wavelengths.  Optionally the AvaLight-DH-BAL-CAL can be ordered to have a more balanced spectrum in the 200-1100nm range. Also new is the AvaLight-D-CAL for UV range calibrations only (200-400nm)The calibration files can be imported in the AvaSoft-IRRAD application software, developed to turn your spectrometer system into a spectroradiometer. A special version of the calibrated light source, the AvaLight-DH-CAL-ISPXX, is available to couple the AvaSphere-XX-IRRAD integrating sphere to the light source (XX=30, 50, 80).The AvaLight-DH-CAL cannot be used as an illumination source for spectral absorbance, transmittance and reflectance measurements.
