Far infrared waves
WebThe Herschel Space Observatory's mission has been designed to unveil a face of the early Universe that has remained hidden until now. Thanks to its ability to detect radiation at far infrared and sub-millimetre wavelengths, Herschel will be able to observe dust obscured and cold objects that are invisible to other telescopes. WebJan 1, 1973 · The emitted waves may be coherent or incoherent according to the particular generation mechanism. Far-infrared waves lie in the spectral region between wavelengths of 10 and 2000μm. Although harmonic generators, together with hot-body radiators, enabled the extension of research in the far-infrared, the need for powerful sources comparable ...
