Dear List
I turn to you again for your magnificent support request
We have in a confocal microscope LEICA TCS LSI which has the relatively
high center of gravity (since it has a optosplit and additional CCD
camera), and was mounted on a passive anti-vibration system (newport)
This system significantly reduces vibrations, however randomly microscope
eventually presents some movements,
We think that maybe some of the wires connecting the various devices can
generate these vibrations, but do not know what could be the best way to
prevent these movements
any suggestions to fix wires or any other device that could introduce these
vibrations will be much appreciated (we discard the air conditioned)
best regards
Jorge

Jorge,

I would suggest that you check out the equipment that is generating the
vibrations.

Years ago I was working on a vacuum detector that was making a huge
racket.  I touched one of the tubes inside it's cabinet and the racket
went away.  It came back when I removed my finger.  So, I grabbed a
large zip tie and tightened it around the tube. I did not attach the
tube to anything I just wrapped the zip tie around it and the additional
weight of the zip was enough to change the resonance of that tube and
permanently stopped the sound ( and vibrations) generated by that tube.

That is why I am suggesting that you check out the equipment at the
other end of those cables. Another thing to try would be to attach an
anchor bar to the legs or frame of your isolation table (not to the
table top!) and anchor the wires to this bar (zip ties, cable clips
etc..  Assuming that the bar is sufficiently stiff and massive it will
absorb the vibrations and transmit them to the table's legs prevent the
vibrations from traveling further along the wires to the microscope.

Call me or email me if you would like to discuss this further!

Cheers,
Chris

Have you eliminated any source of vibration (e.g. the fan in CCD camera) on the optical table itself? Whilst wires are theoretically capable of transmitting vibrations, I've never found them to be the culprit in any practical situation.  It might help to narrow down the source if you can find out what frequency they are - the computer-like fans you tend to get in cameras tend to be in the 1000-3000 RPM range.

cheers,
David
