The invention relates to a device for applying a liquid immersion agent into a gap () between a microscope objective () and a sample () to be examined under the microscope, wherein the device has a blasting device () which is designed to introduce the immersion agent laterally into the gap () in a jet (), and the blasting device () is designed to spray the immersion agent into the gap () in the form of a vapor or spray mist jet ().

Apparatus and method for applying a liquid immersion medium into a clearance between a microscope objective and a specimen to be examined under the microscope

The invention relates to a microscope, having: a specimen chamber for a specimen (); at least one microscope objective (); one motor driven objective changer (), which, for the purposes of changing a microscope objective, moves the least one microscope objective () through a change volume (); a control device () controlling the objective changer (); and an apparatus for applying a liquid immersion agent into a gap () between the microscope objective () and a specimen () received in the specimen chamber, said apparatus having a jet device () which is designed to introduce the immersion agent in a jet () laterally into the gap (), the jet device () having an operating position (B) for laterally introducing the immersion agent into the gap (), in which position the jet device () is located in the change volume (), the jet device () is coupled to a drive () for adjusting the location of the jet device (), and the control device () is connected to and configured for control of the drive () in order to control the drive () in preparation for the microscope objective change such that said drive moves the jet device () into a parking position (P), in which the jet device () clears the change volume (), then to control the objective changer () to change the microscope objective and subsequently to actuate the drive () so that said drive brings the jet device () into the operating position (B).
