Nouveau spectrographe auto-construit

Post by Ulisse Quadri »

Bonjour a tous,
nous avons enfin terminé la construction de notre spectrographe. Je joins quelques photos du projet et de l'instrument. Ses caractéristiques sont:

Type Littrow
reseau 2400 lignes/mm
Distance focale de l'objectif 185 mm
fentes jeton de Jeulin.

Merci pour votre attention cordialement.

Ulisse

Ulisse,
A very impressive construction! Looks like CNC machined blocks
Look forward to seeing your results.
Do you intend to fir a reference lamp?

Well done!

Many thanks, I am honored for this appreciation from You,
yes, some blocks are made on a CNC milling machine (even the homemade one), others are made on traditional machines in my hobbyist workshop.
Even the anodizing and coloring was done in-house with simple equipment.
I have prepared a special seat for the reference neon: it is the hole that can be seen in the second image of the project.
We hope for good results.

Bonjour Ulysse,
Effectivement le design est assez réussit, bravo pour cette construction. C'est bien solide ? Maintenant il faut voir les spectres.
Bon ciel

Merci encore Ken et Bertrand,
c'est bien solide? Déjà les amis de mon club d'astronomie se moquent de moi parce que je fabrique des instruments solides et lourds. Vais-je probablement obtenir cette renommée ici aussi?
J'ai fait quelques spectres d'Altair et de Gienah, mais je ne suis toujours pas capable de les élaborer si ce n'est de faire un simple graphe avec Visual Spec...
A bientôt.
