Claims
- 1. An inverted optical microscope, comprising a unitary closed housing of generally U-shape and characterized by a horizontal base portion and by two integrally related spaced upstanding legs and defining an interior space for optical elements and ray paths, optical elements contained within and carried by said housing, a rugged specimen table resting on spaced points on the upper ends of said legs and spanning the space between and interconnecting said legs, whereby said housing and thus-connected table exhibit the mechanically stable form of a right parallelepiped with a side-access opening in the space between said legs, lens-carrier means vertically adjustably carried by said housing within the space between said legs and beneath said specimen table, observation-tube means mounted on the top of one of said legs and providing ray connection with the optical elements within said housing as well as an unimpeded direct view of a specimen on said specimen table, said direct view being over said observation-tube means upon slight shifting of an observer's line of sight without substantial head movement, and light-source mounting means on the other of said legs for mounting a specimen-illuminating light source external to said housing.
- 2. An optical microscope according to claim 1, wherein said light-source mounting means comprises a side-wall opening on at least one side wall of said other leg with attachment means for a source of light for incident illumination, and a tube which contains a diaphragm extending between said other leg and said-lens carrier means.
- 3. An optical microscope according to claim 1, in which said light-source mounting means includes a hinge at the top of said other leg for swingable support and positioning of a source for transillumination of a specimen on the table.
- 4. An optical microscope according to claim 1, in which said other housing leg includes an attachment tube for removable mounting of a miniature-film camera means, and means including a semitransparent mirror carried by said housing and externally actuable to divide part of the observation ray into a photographing ray when in photographing position.
- 5. An optical microscope according to claim 1, in which a projection camera is integrated into the other housing leg, the imaged field of said projection camera being observable at a screen surface carried by said housing beneath said observation-tube means and therefore facing the observer.
- 6. An optical microscope according to claim 5, in which said one housing leg contains the projection camera and at the same time the attachment tube for a miniature-film camera, and in which a mirror carried within said housing is externally actuated to enable selective use of one to the exclusion of the other of such cameras.
- 7. An optical microscope according to claim 1, in which said other housing leg is provided with an interchangeable lateral cover plate on which optical elements necessary for special purposes are mounted.
- 8. An optical microscope according to claim 1, in which said optical elements form an intermediate image within said housing, and wherein at the location of the intermediate image of the beam leading to said observation-tube means, said housing has an opening to receive a slide which contains line figures for super-position on the image of the observed specimen.
- 9. An optical microscope according to claim 1, and clamping means to secure said table and legs at said points.
- 10. An optical microscope according to claim 9, in which said points comprise three substantially cylindrical pins fixed to and projecting down from said specimen table, each said pin engaging in a corresponding recess on the top of said housing legs.
- 11. An optical microscope according to claim 10, in which said pins and recesses have coacting bevel-cam surfaces which react to secure said table to said legs in response to a single lateral thrust, and in which said clamping means comprises a single clamping screw reacting between one of said legs and said table for applying said thrust to said table.
- 12. An inverted optical microscope, comprising a unitary closed housing of generally U-shape and characterized by a horizontal base portion and by two integrally related spaced upstanding legs and defining an interior space for optical elements and ray paths, optical elements contained within and carried by said housing, a specimen table resting on spaced points on the upper ends of said legs and spanning the space between and interconnecting said legs, whereby said housing and thus-connected table exhibit the mechanically stable form of a right parallelepiped with a side-access opening in the space between said legs, lens-carrier means vertically adjustably carried by said housing within the space between said legs and beneath said specimen table, observation-tube means mounted on the top of one of said legs and substantially at the plane of said specimen table and providing ray connection with the optical elements within said housing as well as an unimpeded view of a specimen on said specimen table, and a light-source enclosure with a cantilevered outwardly offsetting tubular connection to the other of said legs for thermally isolated mounting of a specimen-illuminating light source external to said housing.
