The System 273 binocular and 373 trinocular microscopes offer 25% greater magnification, 15% greater field of view, and 20% greater working distance than traditional models. They also provide a total optical magnification of 270X. The System 373 provides a digital magnification of 400X. Magnification of both models can be further increased with the use of eyepieces and accessory lenses. The smaller, sleeker body of the 273 and 373 microscopes occupy a lesser footprint on the work surface. Working distance is 2 in. greater than that of traditional binocular and trinocular scopes when used with a 0.5X reducing lens.
