Absolute Cavity Pyrheliometers

ISO-CAL North America operates two Primary Standard Absolute Cavity Pyrheliometers, traceable to the WRR (World Radiometeric Reference). The Absolute Cavity Pyrheliometer is the Primary Standard reference instrument to which all pyranometers and pyrheliometers are traceable. 

The FEL Standard Lamp provides absolute calibration of spectral irradiance from 250 – 1100 nm, serving as the primary reference for all spectroradiometer and UV radiometer calibrations.
