Hi James,

I noticed that your thorlab quote includes concave CYLINDRICAL mirrors (CCM254-100-G01). This does not appear to be correct (perhaps you noticed already), I think they should be concave SPHERICAL mirrors (Thorlab part No. CM254-100-GO1). The price is much lower ( USD58 per mirror for CM spherical mirrors, compared to USD 165 per mirror for the cylindrical CCM mirrors).

Presumably it's a lot harder to make a good cylindrical mirror than good old spherical ones.

Hopefully you ordered the right parts (USD 200 saving!).

Cheers,
Hamish

When you cost the CCD/CMOS camera, guide camera, and other components (like metric taps, screws, Kapton tape, etc), the cost(s) gets closer to $2.5-3K US.

This is also without the cost of the 3D printed components, so please be sure you have the technical skills/courage and funds before embarking on this project.

Thanks for catching that! Thankfully, I have not ordered anything. I'm about 2 mouse clicks from getting a Atik 414ex mono for this project as well as a UV clear
window for glass cover replacement. As soon as I know what route to take for the 3D-printing, I'll order the THORLAB parts. Thanks again!

I think I'm going to get this for the replacement (UV clear) cover glass for the Atik 414ex:

If its cheaper to order more than 2, Let me know if anyone want additional 25.4mm covers and I'll order extra so the
cost can be spread and is less for everyone pursuing this UVEX project sensor.

I got a quote on these SCOTT WG225 UV transmitting replacement cover glass of $110 USD (90 GBP) each if I buy 2 or $100 USD (80 GBP)
each if buying 5 or more. They are physically 25.4mm round diameter and 1mm thick. Let me know if anybody else is interested in
purchasing these for the UVEX project. I'm ordering them when my Atik 414ex CCD arrives next week.

There are details of the "Calibrex" calibration lamp and guider module on the UVEX website, but I did not see the printing files for the box there

Any update on this guide module? I would like to print one and see.
I have printed the box for a UVEX but not ordered any parts until I think it is viable for me to do so.

Hi Terry,

There are 3 prototypes of the guidance module, in test phase. The results seem good. It is necessary to wait a little longer, the parts will be published in not too long (it is a complete set, which covers the optical, mechanical and electronic aspects).
