Abstract
Microscopes, including viewing and other microscopic systems, employ a hinged, tiltable plane to adjust focus on an object such as a microscope slide. A scanning microscope under computer control, employing such a focusing action, enables unattended scanning of biochips with a simple and economical instrument. Also shown are flexure-mounting of a support plate to define the hinge axis, techniques for automatically determining position and focus, and a rotatably oscillating flying micro-objective scanner combined with the tilting plane focus system. Construction and control techniques are shown that realize simple and accurate focusing. Methods of examination of biological materials are disclosed. Simple and efficient focused scanning with a flying micro-objective of ordered arrays of nucleotides and nucleic acid fragments carried upon a microscope slide or other substrate is discovered.
