The invention contemplates an optical microscope of inverted design and having versatility for application to solve and serve virtually all microscopy problems and needs. The microscope features a particular U-shaped housing with upstanding legs and with integrated optical elements contained within and carried by said housing. A rugged specimen table is removably secured to both legs, and is presented for viewing a specimen on said table via either reflected light or via transillumination, the light source in both cases being so mounted to the exterior of the housing as to be thermally isolated from the housing and from the lens system, the latter being vertically adjustable in the space between the housing legs and beneath the specimen table. Various further features are described.
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.
