Abstract
Abstract A camera comprising an image stage and an object stage each mounted to opposite ends of a camera frame and adjustable relative thereto by means of a set of three spaced apart image stage micrometer means and a set of three spaced apart object stage micrometer means. The image stage and object stage micrometers are located at the vertices of imaginary equilateral triangles, with the defined image stage triangle rotated 60* relative to the defined object stage triangle whereby certain of the image stage and object stage micrometers may be cooperatively adjusted to facilitate focusing of the image. There is also provided a fiber-optic light guiding means having flattened and flared ends for directing light into the side edges of the slide; a light source comprising parabolic and spherical reflectors for developing a high intensity-low heat light source for the fiberoptic means; and polarizing filter means mounted between the fiber-optic light source and the edges of the autoradiographical slide and in the optical path between the slide and the lens system to provide means for maximizing the resolution of light reflected from the slide specimen.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
254 words
A wide field high resolution microscopy camera apparatus comprising: a camera frame having a lower object end and, vertically aligned thereabove, an upper image end; an image stage defining an image plane and including a holder for a photographic film; an object stage defining an object plane and including a holder for a substantially planar object to be photographed; a lens system carried by said camera frame defining an optical axis; means mounting the image stage to the image end of said camera frame including a set of three micrometer means located at the vertices of an imaginary equilateral triangle within the image plane with each micrometer means individually providing for adjustable displacement of the image stage relative to the image end along a line parallel to said optical axis and passing through the associated vertex; means for mounting the object stage to the object end of said camera frame including a second set of three micrometer means located at the vertices of an imaginary equilateral triangle in the object plane with such imaginary triangle being rotated 60* relative to the first named imaginary triangle and with each micrometer means providing individual adjustable displacement of the object stage relaTive to the object end along a line parallel to said optical axis and passing through the associated vertex, whereby each object stage micrometer means may be adjusted cooperatively with the diametrically opposed image stage micrometer means to adjustably rotate, respectively, the object stage plane and the image stage plane about parallel and spaced apart axes.
Claim 2
Dependent Claim
254 words
A wide field high resolution microscopy camera apparatus comprising: a camera frame having a lower object end and, vertically aligned thereabove, an upper image end; an image stage defining an image plane and including a holder for a photographic film; an object stage defining an object plane and including a holder for a substantially planar object to be photographed; a lens system carried by said camera frame defining an optical axis; means mounting the image stage to the image end of said camera frame including a set of three micrometer means located at the vertices of an imaginary equilateral triangle within the image plane with each micrometer means individually providing for adjustable displacement of the image stage relative to the image end along a line parallel to said optical axis and passing through the associated vertex; means for mounting the object stage to the object end of said camera frame including a second set of three micrometer means located at the vertices of an imaginary equilateral triangle in the object plane with such imaginary triangle being rotated 60* relative to the first named imaginary triangle and with each micrometer means providing individual adjustable displacement of the object stage relaTive to the object end along a line parallel to said optical axis and passing through the associated vertex, whereby each object stage micrometer means may be adjusted cooperatively with the diametrically opposed image stage micrometer means to adjustably rotate, respectively, the object stage plane and the image stage plane about parallel and spaced apart axes.
Claim 3
Dependent Claim
124 words
The apparatus as defined in claim 1 for photographing an object mounted on an upper surface of a microscope slide, said object stage comprising: a plate mounted to said camera frame object end by said mounting means and having an aperture aligned with said optical axis, index means fixedly carried by said plate at circumferentially spaced locations about said plate aperture on a side thereof opposite from said camera frame for indexing the upper surface of a microscope slide and means for holding such slide against said index means, whereby an object carried on the upper surface of any slide positioned on the object stage is disposed at the same relative distance from said camera frame notwithstanding variations in the thickness of various slides.
Claim 4
Dependent Claim
77 words
The apparatus of claim 1 for photographing objects carried by a microscope slide further comprising: means carried by said object stage for mounting such a slide, and fiber optics light guiding means having a light emitting end flattened and flared to define a generally elongate face with light exiting substantially normal thereto, said fiber optics means being arranged with said elongate face in close confronting registration with a side edge of the slide for directing light therein.
Claim 5
Dependent Claim
101 words
The apparatus as defined in claim 3, a source of light for said fiber optics light guiding means comprising, a parabolic reflector with a lamp disposed at the focal point thereof, a spherical reflector coaxially disposed in confronting relationships with the parabolic reflector and with the spherical reflector focused at the region of the lamp, an aperture formed at the center of curvature of said spherical reflector and a planar reflector disposed adjacent the aperture of said spherical reflector therethrough, and means directing light off of said planar reflector into a light receiving end of said fiber optics light guiding means.
Claim 6
Dependent Claim
76 words
The apparatus as defined in claim 3, further comprising a first adjustable polarizing filter means disposed between the fiber optics light emitting face and the confronting side edge of said slide, and a second adjustable polarizing filter means disposed between said object stage plane and said camera frame lens system, whereby selective adjustment of said polarizing filter means adjusts the ratio between light reflected from the object to be photographed and unwanted light from other sources.
Claim 7
Dependent Claim
139 words
The apparatus as defined in claim 1, wherein said object stage comprises a plate defining said object stage plane, a plurality of spaced apart elongate alignment pins fixedly mounted to said object end of said camera frame and extending therefrom parallel to the optical axis, said object stage plate being provided with a corresponding plurality of pin receiving openings into which said alignment pins extend for generally aligning the object plate to said camera frame, said set of object stage micrometer means being carried by said camera frame and each having an adjustable portion movable relative to said frame along said line passing through the imaginary triangle vertex of said object stage for abutment with said object plate, and means associated with each alignment pin for continuously urging said object plate toward the object end of said camera frame.
Claim 8
Dependent Claim
149 words
The apparatus as defined in claim 6, wherein said image stage comprises a plate defining said image stage plane, a second plurality of spaced apart elongate alignment pins fixedly mounted to the image end of said camera frame and extending therefrom parallel to said optical axis, said image stage plate being provided with a corresponding plurality of pin receiving openings into which said alignment pins extend for generally aligning such plate to the camera frame, said set of image stage micrometer means being carried by said camera frame at the image end thereof and each having an adjustable portion movable relative to said frame along said line passing through the imaginary triangle vertex of said image stage for abutment with said image plate, and means associated with each of the second plurality of alignment pins for continuously urging said image plate toward the image end of said camera frame.
