WebTo calculate the emissivity matrix we heat the target to two known uniform temperatures and measure the total radiances of the target (T 2 > T 1), which are converted to target radiance via the calibration lookup table. Assuming that the radiation representing the reflected environment is unchanged, they are eliminated between the two. http://support.flir.com/Answers/A817T/A817-T560472_A-en-US%20Technical%20publication%2060%20Window%20or%20External%20Optics%20Transmittance.pdf
