| 1、 Purpose: |
| The MM-7 upright metallographic microscope is suitable for observing transparent or opaque substances in the electronics, metallurgy, chemical, and instrumentation industries, such as metal ceramics, integrated blocks, printed circuit boards, liquid crystal panels, films, fibers, coatings, and other non-metallic materials. It is also suitable for observation and analysis in pharmaceuticals, agriculture and forestry, public security, schools, and scientific research departments. This instrument is equipped with a falling beam illumination device, a long-distance flat field achromatic objective lens (without cover glass) |
| The large field eyepiece and built-in polarizing observation device have the characteristics of beautiful appearance and easy operation |
