Abstract
Abstract The invention contemplates a method of microscopic analysis of biological, metallurgical or other specimens, wherein an image copy of a comparison or reference object is used to produce a comparison image in the image plane of the microscope eyepiece. A direct side-by-side comparison can then be made for the unknown or unclassified specimen, against the image copy, which may be two adjacent image copies, displayed alongside the unknown, to enable a judgment as to the resemblance between the unknown and one or the other of the two image copies.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
51 words
In the immunological-fluorescence method of using a microscopic to investigate a prepared object carrier, the improvement which comprises using micro-photographic images of two different preselected-strength reactions to produce in the field of view of said microscope two reference images at the same time and directly adjacent the microscopically produced object image.
Claim 2
Dependent Claim
51 words
In the immunological-fluorescence method of using a microscopic to investigate a prepared object carrier, the improvement which comprises using micro-photographic images of two different preselected-strength reactions to produce in the field of view of said microscope two reference images at the same time and directly adjacent the microscopically produced object image.
Claim 3
Dependent Claim
18 words
The method as claimed in claim 1, in which each of said micro-photographic images is on a slide.
Claim 4
Dependent Claim
22 words
The method as claimed in claim 1, in which both of said micro-photographic images are on separate areas of the same slide.
Claim 5
Dependent Claim
25 words
The method as claimed in claim 1, in which said images are produced directly adjacent each other in the field of view of said microscope.
Claim 6
Dependent Claim
21 words
The method as claimed in claim 1, in which the reference images are produced directly adjacent the microscopically produced object image.
Claim 7
Dependent Claim
27 words
The method as claimed in claim 1, in which the reference image covers a smaller portion of the field of view than that of the object image.
Claim 8
Dependent Claim
27 words
The method as claimed in claim 1, in which one of the reference images shows a negative reaction, and the other reference image shows a medium reaction.
Claim 9
Dependent Claim
19 words
The method as claimed in claim 1, in which the two different reference images are produced adjacent each other.
Claim 10
Dependent Claim
13 words
The method as claimed in claim 1 in specific application to cellular differentiation.
Claim 11
Dependent Claim
15 words
The method as claimed in claim 9, in which the cellular differentiation is blood-image differentiation.
