Abstract

An immersion objective comprises an objective body in which optical components are accommodated, at least one immersion fluid tank and at least one objective-body coupling connection on the objective body. The immersion fluid tank can be supported in a detachable manner via the objective-body coupling connection. At least one pump is supported via the objective body, wherein the pump is arranged in order to convey immersion fluid from the immersion fluid tank to an objective front side. A control electronics component is supported via the objective body and is configured to control the at least one pump.
