Abstract
A process for photographing microscopic objects with consideration of exposure time values to be determined and for making visible a spatially variable measurement spot and an exposure format making before and after the exposure is indicated, which process proceeds according to the process steps which are prescribed in accordance with the claims. In addition to this, a microphotographic device for carrying out the process or processes, having a microscope tube with return mirror device and a photographic eyepiece, downstream of which there are disposed a device for measuring the brightness of an object detail as well as markings to make visible at least one detail measurement field and the image field of a camera in the observation beam path, the detail measurement field being adjustably constructed in the functional plane, which is a plane conjugate with the eyepiece intermediate image, in the region associated with the entire image field, and the detail measurement diaphragm being disposed in a first illumination beam path, as well as a carrier containing the image field marking being disposed in a second illumination beam path, and a first beam splitter combining the two illumination partial beam paths being provided, and a second beam splitter being disposed between the camera shutter and the eyepiece optical system of the microscope, in such a manner that the images, transmitted by the combined illumiation partial beam paths, of the detail measurement diaphragm and of the image field marking are reflected into the eyepiece intermediate image plane in a superposed manner, is described, graphically represented and claimed.

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.
