Summary[edit]

Analyse spectrale : focalisation par un réseau courbe.

L'utilisation d'un réseau courbe pour l'analyse spectrale permet de travailler avec une source ponctuelle et une distance réduite, les rayons déviés par le réseau convergent sur le cercle de Rowland.

La couleur des rayons n'est là que pour les distinguer ; ils ont en fait la même couleur, celle de la source. La couleur observée en un point du cercle de focalisaiton est due aux interférences entre les rayons.

Spectral analysis: focalisation by a curved diffraction gratting.

The use of a curved gratting for spectral analysis allows working with a point source and a reduced distance, the reflected rays converge on the Rowland circle.

The colour of the rays is just here to distinguish them; their true colour is the colour of the source. The colour observed at a given point of the circle is due to the interferences of the rays.
