Trinocular Reflective Metallurgical Microscope
MJ21 is a upright metallurgical microscope with reflecting lighting applies to the microscope observation of non-transparent objects. This instrument is equipped with epi-illumination system, plan achromatic (no cover glass) objectives in long working distance, wide field eyepieces and built-in polarizing observation device. With the features of high image sharpness, good contrast and easy operation, MJ21 is an ideal laboratory microscope for the research of metallography, mineralogy, precision engineering and electronics. It is widely used in universities, scientific centers, laboratories, factories and other institutes.
