Abstract
A transmitted light and/or incident light inverted microscope is described, which comprises a 'C'-shaped microscope basic body (G), the free opening (Of) of which is directed toward the observer (B). A particular construction feature is the preferably vertical disposition of the following microscope parts along the optical microscope axis (4)--from bottom to top--: Objective (1) - object (3) - condenser (2) - center (19a) of the binocular housing (5) (FIG. 1a). At the pure incident light inverted variant (FIG. 1c) the condenser (2) is dispensed with. The multiply bent imaging beam path runs through the inside of the basic body (G). According to an alternative solution the binocular housing (5) is disposed at the front face of the stand arm (A) directed toward the observer (B) (FIG. 1b). According to all embodiments, the observer (B) is provied with a direct view into the binocular (5) as well as onto the object (3) and to the adaptable top mounted or, respectively, side mounted attachment modules, such as, for example, a viewing screen (22) while in ergonomically optimum microscoping position (FIG. 4). In addition, the observer (B) without changing his position can directly and unimpededly perform manipulations at the object (3) from the free opening (Of) as well as perform in an optimum way all necessary operating functions of the new provision. Additional provisions without exception are adapted to the part regions of the stand base (F) and/or the stand support (T) and/or the stand arm (A) for ergonomic reasons.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
