Hello,
Does anyone want to make me an offer for my ALC60 laser head? The head needs aligned ( Not too hard to do once you get the hang of it ) but was doing 120mW multiline when it was aligned. Ballast resistor in the head needs screwed back into it's mount, I can't find screws for it - but it'll be a 2 minute job once you do find some. OC end mirror mount has a screw missing - 4-40 Hex screw will replace it. The thermal interlock switch is also broken, but it will work without this.
Tube is gas intact (tested with a HeNe PSU). Make an offer on this. With a little time spent aligning it should be lasing away happily again.
I've also got:
One ALC60 Torodial cathode transformer. Make me an offer on this.
One bare melles griot HeNe tube, 1-2mW. (£10)
One JDSU HeNe, has a casing with a cable, no connector at the end, 1-2mW. Comes with a nice solid mount too. (£20)
