JDS UNIPHASE HENE LASER TUBE 25" 35mW, HELIUM NEON - eBay (item 180476940167 end time Mar-09-10 06:41:27 PST)

AAARGH ..... if only those damn sellers don't sell just inside USA ..... the Spectra-Phisics 165 looks not so bad, for a water cooled unit ..... some doubts about the usual "we sell it as is cause we can't test it" excuse, but can worth the try .....


..... especially cause the tag say "argon/krypton/15W" , and the inside looks a bit inusual, for me :evil: (but this can always be a personal impression )

oops ..... you're right, i had not noticed it (but i don't know this specific unit, so my mistake)

And now that i look better at the pics ..... am i wrong, or this mean that someone treated the coupler really bad, dismantling the unit ? ..... as far as i remember from similar units, those type of flexible couplers must be in better shape, and not so crunched, in good units .....

Your right.

That is NOT good, that is the brewster stem cover. Now I'd want to tesla it for gas and look at the face of the brewster window, illuminating it with a hene looking for scratches. While those bellows are very fragile and corrode inside from the UV and Ozone, somethings just not quite right, that is a operator error, perhaps adjusting the tube centering wrong while forcing a cover on, or the tube is a bit loose..

Still a great deal on a 265 PSU. Have them cut off the umbilical and ship you the psu and umbilical.., unless you like playing the lottery on the tube.

That teflon tube is there to pressurize the stem with either nitrogen or filtered air, for single frequency or UV work. If its UV, one wonders if the tube has been pushed hard, as UV requires a extra ionization step, ie ARIII+ instead of ARII+

That one has the extra space for a etalon, which is not there, and the end bell looks nasty inside...

I'd say 1 in 4 chance its still ok, not my kind of odds...

That yellow He-Ne looks amazing

Are yellow He-ne's alot more stable than the DPSS ones from CNI etc?

But then again I guess that's the price you pay for having a yellow laser in such a small package, that he-ne is hardly portable.

Click to expand...

Much more stable, as in 98% of full power at turn on and 100% a few seconds later. You wont even see it change...

Now, 12VDC psus are available. You'd just need a belt pack and some A123 cells.
And by A123, I don't mean the ones at KMart..

^ Gates sealed PB cells, 2V, 6 of them, and you get a very affordable battery pack (or also a belt, as they uses them for old VHS cameras )

BTW, not "Bill" Gates .....

Thanks for posting. A friend of mine bought it..

We'll soon know how fixable it is.. If it needs fixed. Its on a table back home.
My home is 250 miles from where I work... In a town that is NOT home...
&^%$# lousy economy in Ohio...

Steve

^ I did wind up bidding on that.. but at least I lost it to someone who may actually be able to fix it The only reason I even wanted it was because it was 25" long... I would love to have a HeNe that long!!

There's also this item on ebay....
