<p>The object (Probe) may be a live single-celled animal. It rests on a horizontal reflective or transparent plane (Probentrager). The illumination light channels (Beleuchtungskanal) are placed in diametrically-opposed positions on either side of the objective lens (Lz) and the observation channel (Beobachtungskanal). A parallel light beam (LS1,LS2) passes through each illumination light channel and is reflected inward by two curved mirrors (R1,R2). The two beams are brought to a focus (P) under the center of the objective.</p> |
