Abstract

A device for optically coupling a first optical element to a second optical element comprises a first optical element with a first radiation penetration surface; a second optical element with a second radiation penetration surface located across from the first radiation penetration surface; and a chamber delimited by the first and second radiation penetration surfaces and a circumferentially closed side wall which connects the first and second radiation penetration surfaces. The circumferentially closed side wall defines a first sector in the first radiation penetration surface and a second sector in the second radiation penetration surface, the area of the first sector being smaller than the area of the first radiation penetration surface, and the area of the second sector being smaller than the area of the second radiation penetration surface. The device further comprises a feeding conduit to the chamber for delivering index-adjusting liquid; and a discharge conduit from the chamber for evacuating index-adjusting liquid or gas from the chamber.
