Abstract

The present invention relates to an optical arrangement for illuminating objects (1), in particular fluorescent objects, preferably in conjunction with a confocal or a double-confocal scanning microscope, having an illuminating beam path (2) of a light source (3), a detection beam path (4) of a detector (5), and a component (6) which unifies the detection beam path (4). For the purpose of at least largely loss-free union of the light coming from the object (1) into a propagation direction (19), the optical arrangement according to the invention is characterized in that with reference to the beam cross section active for the detector, light of the fist and second partial detection beam can be united at least largely in an overlapping fashion into one propagation direction (19) at the component (6) thereby providing an unified the detection beam path (4).
