Consider: How noisy is the environment? Are you in a basement or an upper
floor of a building? Is there a road with bus or truck traffic nearby? Are
there fridges or freezers or other vibration-causing equipment in the next
room?
A thicker table tends to damp out lower frequency vibrational noise, so if
you have lower frequency noise in the environment then a thicker table
would be better. A thicker and heavier table also tends to be more stable
if it is bumped or leaned on by a user, so overall thicker is better.
My own lab is on a second floors, near a major highway with truck traffic,
with a room full of -80C freezers down the hall with lots of compressors
rattling away. I went with huge active-leveling air floated 18" thick
tables and have had no issues with my confocals and two-photons re
vibration.
