Thomas Digital Stereo Microscopes feature a built-in, high-resolution 8.5 mm ( 1/3”) CCD camera, which can produce images on TVs and monitors with approximately 80% field of view through the eyepiece. A built-in capture card converts an analog to digital signal for easy viewing on either a standard video monitor or computer. The digital stereo microscope features rugged, die-cast metal construction, a trinocular phototube inclined at 45°, diopter adjustment on both eyetubes with interpupillary distance adjustment between 54-76mm and widefield highpoint 10x, 20mm eyepiece. Strong incident and transmitted halogen illumination is provided by a top 12V, 15W bulb and a bottom 12V, 10W bulb, both with intensity control. The working distance is 80 mm without auxiliary objective, and the continuous zoom range of 1x to 4x requires no refocusing through the entire magnification range.  The microscopes also feature plug and play computer applications with simple USB plug and user-friendly image processing and analyzing software. Thomas microscopes feature a 5-year warranty on all parts, 1-year on electrical parts.
