The PMM-3B optical microscope adopts both reflection and transmission lighting methods, and is equipped with a polarizing device. Under reflected light illumination, it can be used for both bright-field and polarized observation, and under transmitted light illumination, 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. The instrument also comes with the option of purchasing the metallographic image analysis software provided by our company, which can be used for measurement, analysis, and rating on a computer.
