The SM745NB binocular stereo microscope provides a 7X-45X magnification range with 0.7-4.5X zoom objectives and 10X focusable eyepieces. Designed for 76mm-collar focus-racks, this head can be used with a wide range of support systems, including our basic table-stands, boom-arm stands, and articulating arms. Different from the standard SM745B binocular head, this microscope uses focusable eyeieces rather than dioptric-adjustable ocular-tubes, and it features a zoom-lock.
