Introduction to Metallographic Microscope DM90/90BD
The metallographic microscope DM90/90BD is suitable for microscopic observation of opaque objects. By adopting an excellent infinite optical system and modular functional design concept, it is easy to upgrade the system and achieve functions such as polarized observation and dark field observation. It can be used to attract disasters, prevent hemorrhoids, and even cause legal dizziness. It can also be used for 7-bite work, such as first hissing, wine picking, and fatigue sharing. 憷 J looks at the rice paste, the rice straw, the ammonia rice husk, the Weng Weng, the southern halo 9, the wall, the eel, the А笪, the americium, the А⒕芄, the grape core, and the Kang Nang look at the Ao XII br/>
