SYSTEM AND METHOD OF MULTITECHNIQUE IMAGING FOR THE CHEMICAL, BIOLOGICAL OR BIOCHEMICAL ANALYSIS OF A SAMPLE

摘要

The invention essentially relates to an imaging system for chemical, biological or biochemical analysis of a sample (10), comprising - a device (40) for supporting the sample (10), - an optical detection device (20), - an illumination device (30), able to emit a monochromatic light beam, and - a large-aperture objective (f1). It is essentially characterized in that the objective (f1) is configured so as, downstream of the sample (10); to focus the exciter light beam reflected at a point (C) situated in the focal plane (FF) of said objective (f1); and to transform the light beam reemitted or scattered into a quasi-parallel beam, and in that the system furthermore comprises a device (70) for selectively shutting off the light beam collected by said objective (f1).
