• the method comprising:
• via a first fan assembly arranged in or at least one first opening of the top side wall, blowing atmosphere into the sample chamber or draining atmosphere out of the sample chamber through the at least one first opening of the top side wall of the sample chamber, and
• allowing atmosphere from inside the sample chamber to exit the sample chamber or allowing atmosphere from outside the sample chamber to enter the sample chamber, through at least one second opening arranged on the bottom side in the bottom side wall of the sample chamber for generating a flow inside the sample chamber of the microscope.
