Anyone else see this questionable E-bay laser?
Buffo
(link:http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7612579452)
"Krypton Argon Laser with brand new bulb!"
ahhh... "Bulb"???? Don't know that I've ever seen an ion laser that
used a "bulb" before...
What's more, I don't think a 643 tube (the smallest available tube that
I know of that works as a mixed gas tube) would fit inside a 532
housing, and we've already discussed why whitelighting a 532 tube won't
work, which makes me wonder what sort of "bulb" was actually installed
by the seller. (Seller claims in the listing to have recently replaced
the tube.) I just don't see how it could possibly be Kr-Ar...
And I don't know where on earth they're selling these things for
"$20,000 new".
My spider-sense is tingling... but to be fair I asked the seller for
pics of the head in operation showing the multi-line whitelight
operation. (I'm not holding my breath though.)

LOL, 'Brand new bulb'.. Awesome :)
I'm still laughing

Well, in all fairness, he does use the word "tube" in the description.
But at 96% Feedback, no model number, no power measurements, no
additional information, really mediocre photos, obviously quite old with
a 150-type power supply, not sure how high it will go. I'd bid $25. :)

lists the colors it emits, no yellow no red listed. Hmm...

This one caught my eye as just last week I received back from Evergreen
Lasers an Omnichrome 643 ar/kr laser that they rebuilt for me. BTW,
professional and an excellent rebuild.. Highly recommended!!!! While
they didnt put in a new "bulb", Evergreen put in new windows, new
beamsplitter, and many other improvements to have the tube speced at
230mw at 8 amps tube current. They also exchanged the optics out from
the original confocal micscropy TEMoo RYB optics, to TEMo1 RYGB optics.
Needless to say, I am very pleased with their workmanship! When shipped
back to me, Evergreen insured the laser for $10K, which should be
ballpark what Melles Griot would charge for a new 643. I do know Melles
Griot wants >5K+ for a replacement tube.
Seller had a Buy It Now price of $4000.00
I would say without a doubt it is a 150 tube as a 643 tube is not going
to fit in a 150 housing.
Patriot is right, where is the red and yellow listed in the
description, only argon lines.
spam@frontiernet.net C what I mean
seemed unreal to me.. He said that new it was indeed about $20k.. I was
wondering if anyone ever did sell those for that much.. sounds a bit out of
the ball bark to me.. 300mW white lights from Laser Physics were only going
for $12k.

Well, at least the seller replied to you. I have yet to receive a
reply to my question...
Either way though, I agree with Sam. 4 negatives with less than 100
transactions, no power measurements, crappy pictures, no model number
(or other info), and contradictory information in the header (Kr-Ar
listed but only argon lines claimed in the color list) tells me to stay
away from this one.

That kind of exaggeration isn't the problem. Everything else is!

You can get 3-5 mW of 488 and 3-5 mW of 568 out of a 60X sized tube,
did that on the pump bench before. But that is in a low gain mode that
doesnt last long and you need to supress 647 and 530 or its squirelly.
DZ laser actually makes a 60K in teh blue yellow for confocal
microscopy. But I doubt this is one of them
