Hi, dusting off some centimeters of dust from my shelf, i found back a box containing a pair of Ar-Ion heads, Lasos model 7890A.
Those units have a sad story on their shoulders ..... they came from a set of 6 old Agfa D-LAB units, that was trashed almost 2 years ago from a big photo company ..... the sad part was that the peoples that trashed them, had already mangled and smashed almost all the units before i found them, including a lot of very professional optics, just for recycle the metals :cryyy: , so i got to save only 3 tubes and one PSU (no remote nor anything other, they wasted also the fiber optic cables cutting them for see if they was copper, damn them) ..... i already sold one of them with the PSU a year ago, so now i have these 2 doing nothing other than rest in a box collecting dust on that shelf.
I took some quick pics of one of them (i was in hurry), if someone want more specific pics, just ask, and i post them in the next days.
I don't know too much about this specific model, only that are multiline "glass bell" units with main tuning on 514nm, and that was produced specifically for Agfa D-LAB serie (a digital printing photolab) ..... they was made for stability, more than for power, so probably you can't get too much from them, maybe 10 or 12mW, mainly in the 514nm wavelenght (if i recall correctly, the 454 / 457nm part was barely 2 mW, and the rest also less) ..... They have their original cable and fan, and over the shutter slider, at open aperture, there's a second slider with an empty hole and a second hole with a polarizer filter in it (in the minilabs they was used with the polarizer in the path, probably without it, you can get some more power, but i don't have a compatible PSU, so cannot test anything) ..... the last time i tried them, before sell the one with the PSU, they was working, but consider that now is at least a year that they don't become turned on ..... does some gas laser expert (*cough*Dave ?*cough* ..... ) know what they can worth without the PSU, actually ? ..... and also, there is someone interested to buy one of them ?
Please consider that i'm in Italy ..... i can ship oversea, but shipping oversea from here can be a real pain you-know-where, for shipping fees with this weight ..... anyway, i'm cleaning up my messy shelfs (i just realized i have too much lasers around ), so probably in the next weeks some other things can pop up for sale .....
