TES devices are special because they can measure the energy of a single photon. That said, you could split the beam 50/50, send half to a photodiode and half to a standard bolometer and work out the average photon energy. | |

Reading on TES tends to categorize them as a special class of bolometer, and it appears that commercial uncooled bolometers already do exactly what I'm describing for the LWIR spectrum (which I assume means they could do the same for shorter wavelengths). | |
