-Some users have reported vibrations, e.g. diffraction-size beads will appear as a diagonal smear.  Assuming you have the system on a floated air table, this is probably due to a combination of the vibration of the camera fan and the vibration-prone nature of ASI's original piezo objective movers.  Some cameras vibrate more than others, and there can be significant variability even within the same brand/type.  PCO cameras seemed to have the worst vibration initiallyin mid-2015 the internal design was modified.+Some users have reported vibrations, e.g. diffraction-size beads will appear as a diagonal smear.  Assuming you have the system on a floated air table, this is probably due to a combination of the vibration of the camera fan and the vibration-prone nature of ASI's original piezo objective movers.  Some cameras vibrate more than others, and there can be significant variability even within the same brand/type.  PCO cameras seemed to have the worst vibration initially, but in mid-2015 their internal design was modified to correct this and now all three cameras seem comparable.  The exact threshold of when vibrations become noticeable depends on the experiment specifics.
