Control system for a liquid filling level and microscope stage including such a system

Abstract

A system for controlling a filling level of a reservoir filled with a liquid includes the reservoir configured to be filled with the liquid at least up to a maximum filling level. The system also includes a probe including a probe body, at least a section of the probe body extending, in a height dimension of the reservoir, from a first position to a second position, the first position being lower than the second position, and the second position being above the maximum filling level, and further including a temperature dependent sensor configured to generate a sensor signal based on a temperature at the second position, the temperature depending on the filling level. The system also includes a controller for controlling the filling level of the reservoir depending on the sensor signal such that the filling level is kept constant.
