Abstract
Abstract An illuminating system for the miniature CCD camera of a direct contact microscope. Light from a light source is channeled through a fiber optic bundle to two half spheres where the light rays are reflected through an observation hole to an object. The illuminated image of the object is directed through a magnifying lens to the CCD camera for displaying on a monitor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
An illuminating means for use in a microscope to illuminate an object to be examined by a miniaturized CCD camera along a viewing axis comprising; a first half sphere having a reflected coating on its interior; a second half sphere having a reflected coating on its interior; a magnifying lens mounted in said second half sphere; an observation aperture in said first half sphere aligned with said magnifying lens in said second, half sphere; a plurality of optical fibers partially surrounding the perimeter of said second half sphere, said first half sphere fitting over said optical fibers and completing a spherical shape with said second half sphere; said optical fibers forming an optical fiber bundle with an end exposed to a light source; a light source for illuminating an object, channeling light through said optical fiber bundle and said individual optical fibers to the interior of said first and second half sphere, the light being reflected off of said reflective coating to illuminate an object.
Claim 2
Dependent Claim
165 words
An illuminating means for use in a microscope to illuminate an object to be examined by a miniaturized CCD camera along a viewing axis comprising; a first half sphere having a reflected coating on its interior; a second half sphere having a reflected coating on its interior; a magnifying lens mounted in said second half sphere; an observation aperture in said first half sphere aligned with said magnifying lens in said second, half sphere; a plurality of optical fibers partially surrounding the perimeter of said second half sphere, said first half sphere fitting over said optical fibers and completing a spherical shape with said second half sphere; said optical fibers forming an optical fiber bundle with an end exposed to a light source; a light source for illuminating an object, channeling light through said optical fiber bundle and said individual optical fibers to the interior of said first and second half sphere, the light being reflected off of said reflective coating to illuminate an object.
Claim 3
Dependent Claim
40 words
An illuminating means as in claim 1 wherein said miniaturized CCD camera is mounted above said magnifying lens and in alignment with said magnifying lens and said observation aperture, where said miniaturized CCD camera is connected to a monitor means.
Claim 4
Dependent Claim
17 words
An illuminating means as in claim 2 wherein said microscope is in direct contact with an object.
Claim 5
Dependent Claim
22 words
An illuminating means as in claim 3 wherein the illuminating light from said first and second half spheres evenly illuminates an object.
Claim 6
Dependent Claim
12 words
An illuminating means as in claim 4 wherein said microscope is portable.
