Abstract
A fluid immersion control system may use a common electrode along with a plurality of sensor electrodes at a distal portion of an immersion microscope objective to monitor electrical resistance of a fluid as an indication of presence of a fluid layer used for immersion microscopy. The fluid immersion control system may activate replenishment of the fluid when the resistance indicates that a diameter of the microscope objective is not immersed in the fluid.
