UV/VIS/NIR Calibrated Light Sources

AvaLight-HAL-CAL

The AvaLight-HAL-CAL is a compact, low-cost light source, calibrated for the VIS region (350-1095nm). As an option, an extended calibration for the NIR spectral range (1100-2500 nm) can be ordered as well. 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, cosine corrector (CC-UV/VIS-CAL) with SMA adapter and a CDROM with the calibration file in ASCII format. The AvaLight-HAL-CAL calibration file can be read in by AvaSoft-IRRAD, the software package developed to make your spectrometer system a spectroradiometer.

A special version of the calibrated light source, the AvaLight-HAL-CAL-ISP-xx, is available to couple the AvaSphere-xx-IRRAD integrating spheres to the light source (xx=30, 50 or 80mm).

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 a PS-24V/1.25A power supply which is also included.

AvaLight-DH-CAL

The AvaLight-DH-CAL is a calibrated light source for the UV/VIS/NIR region (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, cosine corrector (CC-UV/VIS-CAL) 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 lamps 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 higher wavelengths. As an option, an extended calibration for the NIR spectral range (1100-2500 nm) can be ordered as well.

The calibration files can be imported in the AvaSoft-IRRAD application software, developed to make your spectrometer system a spectroradiometer.

A special version of the calibrated light source, the AvaLight-DH-CAL-ISP-xx, is available to couple the AvaSphere-xx-IRRAD integrating sphere to the light source (xx=30, 50 or 80mm).

The AvaLight-DH-CAL cannot be used as an illumination source for spectral absorbance, transmittance and reflectance measurements.
