Bright field & Dark field Microscope MJ33

Metallurgical microscope MJ33 in bright field & dark field is a microscope used in industrial inspection, equipped with bright/dark field objectives, wide field eyepiece and polarizing observation device. The reflective and transmitted illumination system adopts Kohler illumination with clear field of view. It can be used for the observation of semiconductor silicon wafer, LCD substrates, circuit boards, and other kinds of powder solid transparent or opaque industrial test specimen. This metallurgical microscope is an ideal instrument for research of biology, metallurgy, mineralogy, precision engineering and electronics engineering, etc.
