Abstract

Abstract A plural-microscope, preferably having two stereoscopic microscopes, is further provided with a light indicator for projecting onto a specimen supported by the stage a light spot which is substantially smaller than the field of view of each microscope, and the light indicator and stage are made movable relative to each other for varying the position of the light spot on the specimen so that the light spot can be used to identify a selected portion of a specimen to be viewed simultaneously by the microscopes.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 139 words
A plural-microscope comprising, a stand, a stage carried by said stand for supporting a specimen to be viewed, a body mounted on said stand, at least a pair of stereoscopic microscopes mounted on opposite sides of said body for the simultaneous stereoscopic viewing of a specimen on said stage, light indicator means carried by said body between said pair of microscopes and being operative to project onto said stage a spot of light which is substantially smaller than the field of view of each of said microscopes, and means for varying the relative distance between said stage and said microscopes to simultaneously position said light spot at the respective centers of the fields of view of each one of said pair of microscopes to identify a selected portion of a specimen to be stereoscopically viewed simultaneously in said microscopes.
Claim 2
Dependent Claim 139 words
A plural-microscope comprising, a stand, a stage carried by said stand for supporting a specimen to be viewed, a body mounted on said stand, at least a pair of stereoscopic microscopes mounted on opposite sides of said body for the simultaneous stereoscopic viewing of a specimen on said stage, light indicator means carried by said body between said pair of microscopes and being operative to project onto said stage a spot of light which is substantially smaller than the field of view of each of said microscopes, and means for varying the relative distance between said stage and said microscopes to simultaneously position said light spot at the respective centers of the fields of view of each one of said pair of microscopes to identify a selected portion of a specimen to be stereoscopically viewed simultaneously in said microscopes.
Claim 3
Dependent Claim 32 words
A plural-microscope according to claim 1, in which said stage is movable relative to said stand in orthogonally related directions for varying the relative positioning of said light spot and said stage.
Claim 4
Dependent Claim 39 words
A plural-microscope according to claim 1, wherein said light indicAtor means includes color filter means for imparting a selected color to said light spot so that the latter can be readily distinguished from the overall illumination of the specimen.
Claim 5
Dependent Claim 74 words
A plural-microscope according to claim 3, in which said light indicator means includes a light source projecting a light beam toward said stage and condenser lens means to converge the light rays of said beam into said light spot, and in which said color filter means includes a plurality of differently colored filters, and a movable support carrying said filters for the disposition of a selected one of said filters across said light beam.
Claim 6
Dependent Claim 31 words
A plural-microscope according to claim 1, in which said microscopes are articulated on said body for varying the angles at which the optical axes of the microscopes converge toward said stage.
Claim 7
Dependent Claim 185 words
A plural-microscope comprising, a stand, a stage carried by said stand and having a horizontal surface for supporting a specimen to be viewed, a plurality of stereoscopic microscopes mounted on said stand for the simultaneous viewing of a specimen on said stage, each of said microscopes having a predetermined optical axis, said microscopes being mounted such that their optical axes intersect each other to define a plane parallel to said horizontal surface, light indicator means mounted on said stand and being operative to project onto said stage a spot of light which is substantially smaller than the field of view of each of said microscopes, means for effecting relative movement between said spot, said stage and said microscopes to position said spot in said plane which is parallel to said horizontal stage surface and which is located at the intersection of said optical axes of said microscopes, and means for varying the relative horizontal positioning of said light spot and said stage so that said light spot can be used to identify a selected portion of a specimen to be viewed simultaneously in said microscopes.
Claim 8
Dependent Claim 185 words
A plural-microscope comprising, a stand, a stage carried by said stand and having a horizontal surface for supporting a specimen to be viewed, a plurality of stereoscopic microscopes mounted on said stand for the simultaneous viewing of a specimen on said stage, each of said microscopes having a predetermined optical axis, said microscopes being mounted such that their optical axes intersect each other to define a plane parallel to said horizontal surface, light indicator means mounted on said stand and being operative to project onto said stage a spot of light which is substantially smaller than the field of view of each of said microscopes, means for effecting relative movement between said spot, said stage and said microscopes to position said spot in said plane which is parallel to said horizontal stage surface and which is located at the intersection of said optical axes of said microscopes, and means for varying the relative horizontal positioning of said light spot and said stage so that said light spot can be used to identify a selected portion of a specimen to be viewed simultaneously in said microscopes.
Claim 9
Dependent Claim 81 words
A plural-microscope according to claim 6, in which said stand includes a vertical post, a body carrying said light indicator means and having two of said microscopes disposed at opposite sides of said body, said means for effecting relative movement includes rack and gear means for mounting said body in a vertically adjustable manner on said post, and said microscopes are articulated on said body for varying the angles at which the optical axes of the microscopes converge toward said stage.
