Hi. I wrote a wall of text here but the image uploader decided to delete it  |O

Any help identifying this tube? Google doesn't give many hits.

Can i power this from 3V safely?

Thanks in advance.

This IIT is from the Millard/Philips XX1500 range. Commonly found in medical imaging systems. You cannot find a datasheet for the XX1550 because it is a custom order from an OEM but the 1500 series specs should suffice. Exceeding an IIT’s maximum voltage is unwise and can lead to inverter failure. Personally I would run the IIT at the stated nominal 2.7V using a suitable regulator circuit. I would not use a 3V3 regulator as that is too close to the maximum permitted voltage. You could use a 3V3 regulator with a silicon diode in series with its output though  ;)

Datasheet is here....

Safe supply range is 2.0V to 3.4V. Do not exceed 3.4V !

Thank you, Fraser!

I managed to heat up the fibreoptic bundle and free it from the CCD. It's only held on with epoxy on the edge and oil on the optical surface.

If i get to the point of attaching this to another CCD, any tips on what kind of oil that is suitable - will standard mineral oil do?

If the new CCD ends up being smaller size, i wonder if i can machine the fibreoptic piece smaller on my CNC milling machine. I guess i need some diamond tools and patience :)

Not my speciality. That is a question that may get an answer on the main forum as there are lots of optics experts there.
