Uvex build log

[Thibault N]

Dear all,

I would like to start a thread to log my (along with 2 friends that were at the 2019 spectro star party) efforts to build 3 uvex spectroscopes in a row. The base document I am using is this one: http://www.astrosurf.com/buil/UVEX_project/ and I might use also http://uvex30.000webhostapp.com/calibrex-par-lopex/ later on for calibration (but I might decide to use the readymade Shelyak Neon Argon system + spox for automation).

Regarding the precision parts from Thorlabs, my cart is already full, but I haven't ordered the parts yet, for interested people, here are the references:

I also ordered Kapton-like tape in order to secure the lens from https://www.amazon.fr/gp/product/B073CW9Z3K/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1:

And 3 pass taps for M3 and M4 screws: https://www.manomano.fr/p/tarauds-hss-3-passes-jeu-de-3-tarauds-2988654?product_id=3035169 and https://www.manomano.fr/p/tarauds-hss-3-passes-jeu-de-3-tarauds-2988654?product_id=3035170:

Now, I also started to print all parts 3 times with a fdm printer, using black petg from sunlu (more pictures to come).

I'm interested in the UVEX3 myself and have partially prepared by buying a Atik414ex CCD and this product from Thorlabs:
WG41010 Ø1" UVFS Broadband Precision Window, Uncoated, t = 1 mm

I also purchased a spanner that makes changing the old Atik414ex cover glass with this new UV transparent glass a snap; let me know if you
need the part number for this as well.

I can easily go down to 3600A with the Alpy600 with this sensor set-up; see Aply600&Atik414ex + LISA-IR:

However the UVEX3 will be more powerful by being a purely reflective system. Because I tuned my Alpy600 to get sharp UV/Blue response, my red around H-Alpha suffers.
