The zoom body is the core of stereo and zoom microscopes. When zooming, lenses have to be positioned precisely. Until now, a metal component milled with great care would determine the exactness of this movement and the optical quality of your microscope.
eZoom replaces the mechanical curve with an electronic one. Stepping motors position the moveable lenses precisely and take the tolerances of the individual lenses into account. Each zoom body describes its own zoom curve and captures visibly more details. eZoom follows the base line for image sharpness over the magnification range with a doubled precision, compared to a mechanical zoom body.
Green: depth of field curve, within these parameters, images are in focus
Red: typical defocus curve of a single zoom channel with mechanical zoom curve
Blue: typical defocus curve of a single zoom channel with electronic zoom curve
