UAI-CCD Camera Stuff

I found the UAI-CCD website many years ago:

https://www.uai.it/ccd/

On the left panel of the page is a flag for Italian & English but only an introductory page exists in English.

I downloaded all the webpages and had “google translate” them into English. This worked except for a few words that could be inferred from the context. Some translation errors: Sockets – clogs, Voltage – tension, you get the idea.

I ordered the CCD chip from FRAMOS in Europe. They quoted me a shipping charge of over $100.00 so I asked them to mail it (no tracking, no insurance) – cost was reasonable and it arrived just fine in a few weeks.

Most of the parts were able to be sourced from US suppliers. The only thing I could not find was the “cold box”. It had metric measurements that had to be very precise. Today I would design it in OpenScad and 3d print it. At the time I did not have my 3d printer so I made it from foam and fiberglass – which should be insulated better than the specified box.

The software to open the printed circuit boards is FIDO cad. You guessed it – it’s in Italian (free software). Luckily the website provides enough pictures of the program to enable printing of the files without learning any Italian.

I wired the peltier cooler directly from the power supply – a very high current device and I saw no need to run it through a trace on the camera chip board.

So far the camera “sees” shades of light and dark. I won’t be able to focus an image on it until I complete the assembly. I still need to make a glass cover plate for the cold box and create a controller for the peltier chip.

I had originally built a (very physically large) power suuply for the camera. The ps was larger than the camera! It was a +/- 15V dual stage built up from components. I felt this was the best way to get an extremely low ripple noise power supply. You can see it in one of the pictures above. I have since figured out that I can achieve the same or better level of ripple using 2 single chip voltage controllers in series for each voltage. The design is done – it’s on my list of things to make.

My scope is the DSO-2250 USB. Works great.
