Optical system for forming an image of a subject has a source of light for illuminating a subject and optical elements/lenses or mirrors for forming an imaging beam path from illuminating light reflected/scattered by the subject
Optical system for forming an image of a subject has a source of light for illuminating a subject and optical elements/lenses or mirrors for forming an imaging beam path from illuminating light reflected/scattered by the subject
Radiated from a source of light, an illuminating light (7) is directed at an optical element, e.g. a lens (3), for forming an imaging beam path (9) and then from there directed at a subject (4). The illuminating light and imaging light (8) each hit special areas of an optically active surface of the lens.
