Spectral Response

Spectral response of SI series

infrared radiometers. Spectral

response (green line) is

determined by the germanium

filter and corresponds closely to

the atmospheric window of 8-14

µm, minimizing interference from

atmospheric absorption/emission

bands (blue line) below 8 µm and

above 14 µm. Typical terrestrial

surfaces have temperatures that

yield maximum radiation emission

within the atmospheric window,

as shown by the blackbody curve

for a radiator at 28 C (red line).
