“Yes it's the new Touptek cooled mono Astronomy cam ATR585M, has response upto 1100nm with the Sony STARVIS 2 sensor. 90 secs exposure for the IR shot (with sensor cooled to -10 degrees for low noise) and then colour it red and overlay it on top of the initial backside IR shot taken with 1050nm IR LED's. ”
“Yeah public domain is fine and just credit “4e71” I guess, thanks. 🙂”

“So I tried soaking 3 chips in acetone, toluene and paint thinner (acetone, xylene and ethylbenzene mix) for 24 hours and none made any visible difference to the glue but all softened it enough to allow scraping it away fairly easily with a wet wooden toothpick. But all still left visible marks on the rear of the die which were causing IR hotspots. So still hoping for a purely chemical solution I tried hot (80 degrees C) drain cleaner for a couple of hours, then a clean with acetone. That's given the best result so far, still some hotspots left as you can see in first pic, focusing on the back of the die. But focusing past them onto the metal gives a pretty good result now, only the worst of the hotspots are still causing some noticeable flare. But looking pretty good now I think. 🙂So I tried soaking 3 chips in acetone, toluene and paint thinner (acetone, xylene and ethylbenzene mix) for 24 hours and none made any visible difference to the glue but all softened it enough to allow scraping it away fairly easily with a wet wooden toothpick.
