THE PROBLEM:
We study living cells and have some problems with temperature
controlling. It seems that a variation of less than 0.1 degree C influences the
focal depth too much. The focal depth changes sometimes 0.5 um.

THE SET-UP:
  1) 60x/1.4 Nikon (on a Biorad MRC 1000/1024)
  2) an objective heater and its controller.
  3) cells on a Glass Bottom Petri dish (MatTek)
  4) a 'warm table' for the petri-dish and its controller

The heater controllers keep the temperature on 37 C with an accuracy
of less that 0.1 C so, that seems to be good enough.

THE QUESTION:
  1) Has anyone similar problems?
  2) Did anyone solve the problem?


Thank for your reply, Erik Manders
