Claim 13:
14. The optical spectrometer of claim 13 wherein the processing of the power curve provides an output satisfying a solution to the equation of:

[ε1(λi)][R2(λi)][IBB(λi,Tj)]=[P(Tj)]

for R2(λ2)
where:
ε1(λi) is the emissivity of the emission source;
R2(λ2) is the unknown reflectance or transmittance of the sample object;
P(Tj) is the power curve for temperatures (Tj); and
IBB (λi, Tj) is radiation spontaneously emitted by a blackbody at the temperature of the emission source as a function of wavelength λi following Planck's law.
