Nice work Pierre!

See if you can go to 3500A (Christian has gone to almost 3300A!)....I can get to 3610A with my Alpy600 after replacing the glass cover of my Atik414ex with
a UV clear one...the grism and astigmatism limits me going much below 3600A.

Hello at all,

Very nice and interesting results Pierre, you are showing to us a good work with this great instrument, the UVEX.

James, are possible that you be able to tell me the address for replacing the glass cover of ATIK CCD by C.Buil, please ? I'm interested in change it, but don't find the link.

Many thanks, Joan.

Bonjour Pierre.
Ton réseau à 1200 traits est blazé à quelle longueur d'onde?
Est-ce le même réseau que tu as utilisé pour UVEX-->IR?

Cdlt,
Ibrahima.

To: Joan,

RE:"James, are possible that you be able to tell me the address for replacing the glass cover of ATIK CCD by C.Buil, please ? I'm interested in change it, but don't find the link."

Here is what I used from the invoice I received from Thorlabs:
"WG41010 Ø1" UVFS Broadband Precision Window, Uncoated, t = 1 mm 1 $91.14 $91.14 USD" (I think the price went up slightly!)

Here's a link to the Thorlabs web page that lists it:
