Something I haven't seen addressed yet is harmonic noise produced by the air handler system. Make sure that whatever system that you use is silent, and that the air flow is not directed toward your vibration isolation tables. Both conditions can set up harmonic noise in your imaging systems. I run an E. M. core, but this also translates to high magnification optical microscopy. Noisy air handlers and pulses of air hitting your imaging equipment can affect your images.

Dear All,
Not a very scientific (though who knows) but still an important (in terms
of comfort) question about the climatization of microscopy rooms. We are
just in the middle of discussions about the arrangement of our new
microscopy rooms. Most of the things are clear, however the planning team
suggested a solution for the climatization that is new to me and I wanted
to enquire whether anyone of you had experience with similar systems. In
the "conventional" arrangement the cold air comes in somewhere at the
ceiling and I think there is a general consensus that it is better if it
is well distributed and not simply blown in into one direction. Our
planning team however suggests a new solution, where the cold air would be
blown in (through some canvas tubes) close to the bottom/floor. The warm
air (that goes anyway upward) is sucked at the ceiling. According to them,
although this systems creates a height-dependent temperature gradient
(cold bottom, stable 22 C at the microscope level and warmer at the
ceiling) but with this one can avoid the continuous mixing/turbulence
where both the blowing in and the sucking away happens on the ceiling
(conventional solution). Now, in theory this sounds good but we are
somewhat skeptical how well this system works in practice and what the
users say if their feet has colder (approx. 16-18 C) temperatures then
their body. In a few weeks we will have the opportunity to check a similar
installation, but I'd really appreciate if you could share your
experiences with us. Obviously this is a important decision for us so any
feedback is welcome.
Thanks Gabor
