Abstract: Microscopes, including viewing and other microscopic systems, employ a hinged, tiltable plate to adjust focus on a flat object such as a microscope slide or biochip by motion, achieved by tilting, which is substantially normal to the focus point on the plane of the object. By employing two such tiltable arrangements, relatively long scan lines of e.g., flying objective, single pixel on-axis scanning can be accommodated. The tilting support plate is specifically constructed to provide tailored locations for different objects in series along the Y axis of the plate. The plate can accommodate heaters and cooled plates and/or the flat object being examined. In a fluorescence scanning microscope, locations are specifically adapted to receive microscope slides and biochip cartridges such as Affymetrix's “Gene Chip®”. A scanning microscope under computer control, employing such a focusing action, enables unattended scanning of biochips with a simple and economical instrument.
