Abstract
Abstract A direct-view stereoscopic confocal microscope including a light source, an aperture plate, image collector, and first and second vibrators. The light source is used for illuminating a portion of a specimen and the aperture plate is used for passing a portion of the light emanating from the light source onto a portion of the specimen. The image collector is optically coupled to the illuminated portion of the specimen and acts to separate the image created by the illuminated portion of the specimen from the light illuminating the specimen. A first vibrator is coupled to the specimen for vibrating the specimen along a first axis and the second vibrator is coupled to the image collector, and synchronized with said first vibrator, for vibrating the collecting means along a second axis.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
107 words
A direct-view stereoscopic confocal microscope, comprising: a light source for illuminating a portion of a specimen, an aperture plate optically disposed between said light source and said specimen, said aperture plate including an aperture for passing a portion of the light emanating from said light source onto the portion of said specimen, means, optically coupled to said illuminated portion of said specimen, for collecting an image created by said illuminated portion of said specimen, first vibrating means coupled to said specimen for vibrating said specimen along a first axis, and second vibrating means coupled to said collecting means for vibrating said collecting means along a second axis.
Claim 2
Dependent Claim
107 words
A direct-view stereoscopic confocal microscope, comprising: a light source for illuminating a portion of a specimen, an aperture plate optically disposed between said light source and said specimen, said aperture plate including an aperture for passing a portion of the light emanating from said light source onto the portion of said specimen, means, optically coupled to said illuminated portion of said specimen, for collecting an image created by said illuminated portion of said specimen, first vibrating means coupled to said specimen for vibrating said specimen along a first axis, and second vibrating means coupled to said collecting means for vibrating said collecting means along a second axis.
Claim 3
Dependent Claim
42 words
The direct-view stereoscopic confocal microscope of claim 1, further including means optically disposed between said light source and said aperture plate, and spaced apart from said aperture plate, for focusing the portion of said light onto said aperture of said aperture plate.
Claim 4
Dependent Claim
65 words
The direct-view stereoscopic confocal microscope of claim 2, wherein said aperture plate includes a plurality of apertures and said focusing means includes a plurality of lens means, each said lens means respectively associated with an aperture of said aperture plate, and wherein each said lens means is adapted to focus light emanating from said light source onto its respectively associated aperture in said aperture plate.
Claim 5
Dependent Claim
44 words
The direct-view stereoscopic confocal microscope of claim 3, further including rotating means coupled to said aperture plate and said focusing means wherein said rotating means is adapted to rotate said aperture plate and said focusing means in synchronism about a common axis of rotation.
Claim 6
Dependent Claim
32 words
The direct-view stereoscopic confocal microscope of claim 1, further including objective means optically disposed between said aperture plate and said specimen for focusing said light passing through said aperture onto said specimen.
Claim 7
Dependent Claim
72 words
The direct-view stereoscopic confocal microscope of claim 5, wherein said image collecting means further includes a quarter wave plate disposed between said aperture plate and said objective means and a polarizing beam splitter disposed between said aperture plate and said light source, said quarter wave plate and said polarizing beam splitter adapted to collect said image by separating the light scattered from said specimen from said light emanating from said light source.
Claim 8
Dependent Claim
18 words
The direct-view stereoscopic confocal microscope of claim 1, wherein said first and second axes are generally mutually perpendicular.
Claim 9
Dependent Claim
18 words
The direct-view stereoscopic confocal microscope of claim 1, wherein said first and second vibrating means vibrate in synchronism.
