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

Abstract

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. Besides the mentioned specifications different microscopical observation methods, i. e. transmitted light bright field, incident fluorescence, are possible. The system can be used for all samples which are prepared on standard slides.
