Radiation Calculator

To run the Radiation Calculator, click the Radiation Calculator button on the right side of the Edgar window. This will present a panel with controls for blackbody temperature and emissivity, and for the curve starting point, ending point, and resolution. Once you have the controls set, press the Generate button and Edgar will generate the blackbody curve. These controls are interactive, so that you can change the temperature after you have generated the curve, and the curve will automatically be adjusted. The Edgar Radiation Calculator calculates blackbody radiation as a function of Emissivity, Temperature, and Wavenumber using this function:

Radiation = 100 * Emissivity * C1 * (Wavenumber*100)³ / e^{(C2 * Wavenumber*100 / Temperature) - 1)}

where 0 < Emissivity < = 1

Wavenumber is in cm^-1

Temperature is in K

C1 = 2 * H * C * C

C2 = H * C / K

C = 2.99792458E8 [m/s]

H = 6.62606896E-34 [J s]

K = 1.3806505E-23 [J/K]
