ARRANGEMENT FOR THE MANUAL ADJUSTMENT OF A FOCUS POSITION ON MICROSCOPES

摘要

The invention relates to an arrangement for the manual adjustment of a focus position on microscopes with a motorised focus drive. According to the invention, the arrangement comprises a first operating element for specifying an adjustment path length and a second operating element for specifying an adjustment speed. Both operating elements are preferably embodied as rotating knobs, whereby an adjustment path length for the focussing movement is specified with the rotation angle of the first rotating knob and with the rotation angle of the second rotating knob, an adjustment speed for the focussing movement is specified. A change in the rotation angle of the first rotating knob and a change in the rotation angle of the second rotating knob are proportional to the change in the adjustment path and the adjustment speed respectively.
