Patent ID: 7593118

Claim:
A system that optically controls a work result of a tool and/or that optically guides the tool using a camera coupled to an optics system and having an imaging beam path, and wherein the tool is moved relative to a workpiece, comprising: the optics system including a front lens component and a rear lens component, wherein the front lens component has a location that is farther from the camera than the rear lens component and, a pupil that is located between the front lens component and the rear lens component, wherein the tool has a location at least approximately centrically in an image field of the camera; a mirror that is located in the pupil such that the imaging beam oath is deflected by the mirror, wherein the mirror has a hole therethrough; and a tool support that is located in the imaging beam path, and which passes through the hole in the mirror, in a position that is at least one of a) approximately centrically in the imaging beam path, b) directly within the pupil of the optics system, and c) in a non-imaging optical region of the pupil, wherein for cases b) and c) the tool support is one of not optically depicted and optically blurred in an image formed by the optics system.
