Before describing the fundamentals of spectrally selective coatings, it is necessary to keep in mind that all matter emits radiation. To describe radiation from matter the concept of blackbody is introduced. A blackbody is usually defined as a perfect radiator which absorbs

WebSep 7, 2010 · The blackbody is the best possible absorber and emitter of radiant energy at any wavelength and in any direction. The total (including all wavelengths) radiant intensity and hemispherical total emissive power of a blackbody into a medium with constant index of refraction n are given by the Stefan-Boltzmann law, π I b = E b = n 2 σ T 4. A realization of a black body refers to a real world, physical embodiment. Here are a few. In 1898, Otto Lummer and Ferdinand Kurlbaum published an account of their cavity radiation source. Their design has been used largely unchanged for radiation measurements to the present day. It was a hole in the wall of a platin…

WebWhen blackbodies with these temperatures are mixed, the resulting purple curve is close to but not exactly equal to the blackbody curve (black). Of course a real star has lines as shown by the G2V (solar-like) star spectrum in green.
