Optical coupling device and method
First Claim
1. A device for optically coupling a first optical element to a second optical element, comprising:
- a first optical element having a first radiation penetration surface, the first optical element comprising a prism;
a second optical element having a second radiation penetration surface which is opposite the first radiation penetration surface, the second optical element having one or more sensor fields;
a chamber between the first and second radiation penetration surfaces, the chamber closed by a circumferential side wall which connects the first and second radiation penetration surfaces and the chamber closed except for openings for a feeding conduit and a discharge conduit, the feeding conduit to the chamber configured to supply index-adapting liquid and the discharge conduit from the chamber configured to evacuate index-adapting liquid or gas from the chamber,the circumferential side wall defining a first section in the first radiation penetration surface and a second section in the second radiation penetration surface, the surface area of the first section being smaller than the surface area of the first radiation penetration surface, and the surface area of the second section being smaller than the surface area of the second radiation penetration surface.

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.
