The Apogee cosine-corrected head provides NIST-traceable spectroradiometric measurements of photosynthetic photon flux in µmol m-2 s-1, irradiance in W m-2, and illuminance in LUX. 

The detector collects light for the spectroradiometer via fiber-optic cable. The spectroradiometer then transmits its measurements to a PC where custom software (included) displays the spectrum of the light source. Live data can be saved as a data file suitable for work in other programs, such as Excel or SigmaPlot.
