Cette modification concerne 3 \u00e9l\u00e9ments.<\/p>\n

1 – La base optique n\u00b0101
2 – Le support du miroir M1 (n\u00b0 300)
3 – Le support du miroir M2 (n\u00b0 400)<\/p>\n

Le reste est conserv\u00e9 \u00e0 l’identique. La modification permet les am\u00e9liorations suivantes:\u00a0
1- La translation du miroir M2, qui est dor\u00e9navant sur un chariot \u00e0 roulement \u00e0 bille de type CNC. Lors de la mise au point, le spectre ne bouge quasiment plus en hauteur.
2- Les supports des miroirs M1 et M2 Thorlabs, sont remplac\u00e9s par des supports en impression 3D qui permettent un meilleurs alignement des optiques (en particulier sur l’axe vertical).\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
