Magnaview DC3-420TH / DC5-420TH
Digital Stereo Microscopes

The convenience and versatility of viewing a large image at 10x magnification, then zooming continuously all the way to close details at 40x magnification... or any point in between. Upright, un-reversed 3-dimensional image remains in focus throughout the zoom range. Features top light for incident illumination and a bottom light for transmitted illumination. The DC3-420TH / DC5-420TH come with fully integrated digital cameras in the system (see description below), see Camera Specifications. The stereo zoom microscope is fully functional independent of CCD camera applications. See the Optical Specifications Chart for other magnifications with use of optional auxiliary objectives and eyepieces.
