Abstract

A device for examining chemical and/or biological samples is provided that includes a sample carrier. The sample carrier includes a sample carrier wall through which a sample is examined with the aid of an objective. The objective includes an exit lens that defines a gap towards an outer surface of the sample carrier wall, in which gap a film of an immersion material can be arranged such that the film is in contact with both the outer surface and the exit lens. The exit lens is surrounded by an objective cap. To improve protection of the objective from becoming fouled by the immersion medium, the objective cap includes a capillary channel connected with a suction device for discharging the immersion medium.
