Bonjour \u00e0 tous,<\/p>\n

Le jeu consiste \u00e0 d\u00e9terminer la temp\u00e9rature d’un filtre qui permet de le centrer sur une raie spectrale vis\u00e9e.
\nNous sommes en Calcium K, 393.37nm.
\nLe filtre est un Alluxa 1A (Plut\u00f4t 1.4A).
\nLe filtre est mont\u00e9 dans le four comme montr\u00e9 dans le post pr\u00e9c\u00e9dent.
\nUn spectro Sol’Ex est mont\u00e9 derri\u00e8re le train optique.<\/p>\n

Voici 4 mesures \u00e0 des temp\u00e9ratures du filtre ajust\u00e9es de 7 \u00e0 10C\u00b0.
\nLe but est de centrer le filtre sur la raie CaK; il s’agit de centrer la petite bande sombre (Raie K1) au centre de la bande passante du filtre.
\nCe test est fait dans les conditions \u00ab\u00a0qui vont bien\u00a0\u00bb. J’ai eu moins de succ\u00e8s avec un autre test.<\/p>\n
