The 440-440PLL Zoom Binocular Stereo Microscope with dual LED base from National Optical is a professional-quality stereo microscope for industrial and educational settings. The 0.75-4.5x eyepieces combine with the 10x objective for a magnification range of 7.5-45x, and the overall height adjusts 13.4-17" to accommodate larger objects. The large zoom ratio of 6:1 and a standard working distance of 110mm provide the flexibility to support a large number of potential applications while the addition of an auxiliary lens or substitute eyepieces extend the magnification up to a maximum of 180x.
