Catalogue Note
Physicien suédois, Angström (1814-1874) est le premier à avoir mesuré une radiation lumineuse par une longueur d'onde. Il montre que les radiations du spectre solaire sont comprises entre 0,8 micron pour le rouge et 0,4 micron pour le violet. Il identifie notamment les raies du manganèse, de l'aluminium et du titane. L'unité de longueur qui porte son nom est le dix-millième de micromètre.
Exemplaire bien complet de l'Atlas auquel sont ajoutées deux planches figurant le spectre de l'ultra-violet, d'après A. Cornu.
