Claim:
1. A camera inspection probe for a coordinate measuring apparatus including a housing having an exterior window, the housing comprising: an imaging assembly of the camera inspection probe that is configured to capture an image of an object at an object plane of the imaging assembly; and an illumination assembly of the camera inspection probe that is configured to produce a light beam directed toward the object to illuminate the object, the light beam being directed toward the object plane, wherein the light beam converges to a focal point at a first focal plane outside the housing, the focal point being between the exterior window and the object plane so as to be prior to intersection of the light beam with the object plane, and wherein the imaging assembly is configured to obtain a focused image of a region of the object from reflected light of the light beam produced by the illumination assembly, at a point subsequent to the focal point of the light beam.
