This absolutely calibrated halogen light source is ideally suited for spectral calibration to irradiance in the wavelength range from 350 nm to 1095 nm. Optionally, the calibrated NIR wavelength range from 1100 nm to 2500 nm can be ordered.

The spectral irradiance is absolutely calibrated on the removable cosine corrector, which can be connected to an optical fiber via an SMA connector. The light source is calibrated against a NIST traceable standard. The light source further comes with an ASCII calibration file. AvaSoft Full and the software module AvaSoft-Irradiance make it very easy to perform an absolute calibration with an Avantes spectrometer.

Using the AvaLight-HAL-CAL-ISPxx-Mini variant, the integrating spheres of Avantes AvaSphere-xx-IRRAD (xx=30, 50, 80) can be absolutely calibrated to irradiance.
