Calibration Traceability:

Apogee SI series infrared radiometers are calibrated to the temperature of a custom blackbody cone

held at multiple fixed temperatures over a range of radiometer (detector/sensor body) temperatures. The

temperature of the blackbody cone is measured with replicate precision thermistors thermally bonded to

the cone surface. The precision thermistors are calibrated for absolute temperature measurement against

a platinum resistance thermometer (PRT) in a constant temperature bath. The PRT calibration is directly

traceable to the NIST.

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).
