Abstract

Abstract A process of microscopy and apparatus therefor wherein a slide divided into a specimen area and a reference area is positioned on a microscope stage for visual selection of object points within the specimen area, reference marks are applied to such reference area by a marking device to identify each selected object point, and the reference marks are subsequently aligned adjacent an indicator device to readily relocate such object points for further examination.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 127 words
In combination, microscope means having stage means and lens means, a single microscope slide transversely divided to form a specimen area and a blank reference area and being movably mounted upon said stage means such that an object point within said specimen area may be visually selected for further examination, marking means mounted upon said microscope means for applying a reference mark to said blank reference area at a point spaced from the selected object point of said specimen area by a preselected distance along a preselected direction, and indicating means mounted upon said microscope means at a location spaced from said lens means by said preselected distance along said preselected direction whereby selected object points within said specimen area may be readily relocated for further examination.
Claim 2
Dependent Claim 127 words
In combination, microscope means having stage means and lens means, a single microscope slide transversely divided to form a specimen area and a blank reference area and being movably mounted upon said stage means such that an object point within said specimen area may be visually selected for further examination, marking means mounted upon said microscope means for applying a reference mark to said blank reference area at a point spaced from the selected object point of said specimen area by a preselected distance along a preselected direction, and indicating means mounted upon said microscope means at a location spaced from said lens means by said preselected distance along said preselected direction whereby selected object points within said specimen area may be readily relocated for further examination.
