Omnichrome model 100 PSU question.

[Diachi]

Hello!

Got my new HeCd laser today ! But theres a small problem On the model 100 omni PSU there are 4 lights which tell you the status of the laser. Three of these lights should be lit , thats the power on, Cd heater and He heater lights. When I plug it all in only the power on light comes on ( although the cathode lights and so do some LEDs on the head ). There are two yellow wires coming from the back of the PSU on the low voltage connecter and I think this might be an interlock. Is there anyone here who knows if that is what they are for ?

Any help is much appreciated !

Bore while laser is on, discharge looks more orange than it actually is



Power supply



Anode , discharge is orange because the elctrode on this head is behind the cadmium reservoir, so there is no cadmium at the electrode.

Hope you all liked my pictures !

never mind! Found it that it was an interlock when I saw a little bent but of wire lying next to the plug it works ! pictutes to come.



EDIT: excuse the spelling, awful excited here

Nice He-Cd! What kind of output power does it have? Looks big!

You should get some pictures on a black surface so I can see what you were talking about earlier.... Looks nice though!!!

I wish I had an omnichrome HeCd to keep my liconix company... haha.

Also, if you do find the info on how to change the Cd heater, I would try turning it down a bit. The discharge in the tube looks very white, and you really want a more yellowy color, but then again the very core of my tube is covered so I cant tell if it gets more whitish near the Cd reservoir. Just don't mess with it until you've played with it for a while... haha

The head says 34mW on it, on the label that shows all the factory specs, tube voltage , current and noise etc.

Yeah I will do I think the Cd heater control will be the one beside the voltage control on the side of the head that has a warranty sticker on it, but I'm not sure. After my little He heater incident the disharge is a little more yellowish now anyway .


EDIT: had a look there, can see the beam a little so it's certainly not UV. I'll get some pictures for you though Jason.

EDIT2: the Cd pressure is a little high, I can see it getting slightly brighter ( maybe 3-5mW more ) if I turn the laser to standby ( where the Cd heater goes off ). I'll have a tune at it later
