chAPter | 28 Optical Measurements 519 Table 28.3 Solar and black-body radiation at various wavelengths (after Lawson, 1979) Wavelength band (nm) 0.4­0.8 3­5 8­13 Typical value of solar radiation (Wm ­2 ) 750 24 1.5 Emission from black body at 300 K (Wm ­2 ) 0 6 140 Note: Complete tables of data relating to the spectral power distribution of blackbody radiators are given by M. Pivovonsky and M. Nagel. are based on this work. Although the spectrum of a body around 300 K has its peak at 10 nm, the spectrum is quite broad. However, the atmosphere is effectively opaque from about 5­8 nm and above 13 nm, which means that in prac- tice the usable bands are 3­5 nm and 8­13 nm. Although there is much more energy available in the 8­13 nm band (see Table 28.3) and if used outdoors there is much less solar radiation, the sensitivity of available detectors is much better in the 3­5 nm band, and both are used in practice.
