This is an advanced reflected-brightfield, darkfield and polarizing metallurgical microscopy system. The microscope comes with a quintuple nosepiece, four infinity Plan objectives and a powerful 100W reflected Koehler illumination system, providing brightfield, darkfield and polarizing features. This microscopy system is perfect for metallurgical labs and foundries for silicon wafer inspection, integrated circuit examination, quality control and R&D applications. It is an ideal instrument for metallurgical, mineral and crystal identification. OpticsThe ME600T uses M25 BD objective lenses which provide a larger field-of-view, and can be used with reflected-light darkfield illumination. The quintuple turret allows you to quickly switch between the five lenses. With the included 10X eyepieces, the overall magnification range spans 50X to 1000X.
