The PMM-3BC computer upright optical microscope adopts both reflected and transmitted lighting methods, and is equipped with a polarizing device. Under reflected light, it can be used for both bright-field and polarized observation, and under transmitted light, it can be used for bright-field observation. This instrument has a novel design, excellent performance, and is easy to use and reliable. It can be used in factories, universities, research institutions, and electronic industrial departments for experiments and analysis research in areas such as metallography, mineralogy, crystals, and microelectronics. This instrument can also be equipped with the metallographic image analysis software provided by our company for measurement, analysis, and rating on the computer.
