[A computer-based microscope as the foundation for automated prescreening systems].

The prototype of an automated screening system for cytological preparations is under development. The conditions concerning the handling of such system require the development of a special microscope with certain adjustment functions to be automated. The main specifications of this microscope are: --1 Splitting the light path into two synchronously usable channels for low and high magnification; whereby both images are projected onto two tv-cameras --Additional light path for visual observation --Automated focusing via movement of the microscope objective --Automated supply of immersion oil --Positioning and loading unit for slides --Microprocessor control --Closed and dust-protected design.

Principle and method of kinetic microphotometric enzyme activity determination in situ.

An advanced apparative set-up is described for multipositional microphotometric recording of histochemical enzyme reactions in cryostat sections. It consists of a computer controlled microscope photometer with scanning stage. Measurements on the same tissue section may be performed at 12 preselected positions.
