A Nichols radiometer was the apparatus used by Ernest Fox Nichols and Gordon Ferrie Hull in 1901 for the measurement of radiation pressure.

It consisted of a pair of small silvered glass

kPa). The radiant energy of the incident beam was deduced from its heating effect upon a small blackened silver disk, which was found to be more reliable than the bolometer
when it was first used. With this apparatus, the experimenters were able to obtain an agreement between observed and computed radiation pressures within about 0.6%.

The original apparatus is at the Smithsonian Institution.[1]

This apparatus is sometimes confused with the Crookes radiometer of 1873.

The original papers, with their historical context, have been re-printed in a chapter of the book Quantum Photonics: Pioneering Advances and Emerging Applications.[2]
