Introduction to Metallographic Microscope (Bright, Dark Field, Polarized) DMI40BD
Adopting an excellent infinite optical system and modular functional design concept, it is a multi-purpose industrial inspection microscope. The BMM-30BD metallographic microscope, equipped with bright field, dark field, and simple polarization, has a wide field of view, clear and bright imaging, and comfortable operation. It is an ideal inspection instrument for semiconductor silicon chips, mask templates, LCD substrates, biological, metallographic samples, and other opaque industrial samples.

Professional quantitative metallographic image analysis system, capable of real-time research and analysis of metallographic spectra, such as grain size measurement and grading; Measurement and rating of non-metallic inclusions; Measurement and rating of pearlite and ferrite content; Measurement and rating of graphite spheroidization rate of ductile iron; Analysis and statistics of decarburization layer, carburization layer measurement, surface coating thickness measurement, etc. This includes functions such as image acquisition, storage and display, image enhancement, image segmentation and morphological processing, geometric parameter measurement, image scratch processing, annotation, stitching, depth of field overlay, photo fixed magnification printing, report design, etc.

Characteristics of metallographic microscope DMI40BD
1. Adopting an excellent infinite optical system, it can provide high-quality optical performance;
2. Compact and stable high rigidity main body, fully immersed in motion to the point of motion. The flat field wide-angle eyepiece has a field of view of up to Φ 22mm, making visual observation wider and more comfortable;
4. Mechanical mobile loading platform with built-in rotatable circular loading platform, suitable for microscopic observation and polarized observation of samples of different specifications;
5. Configure high-quality light and dark field objective lenses and dark field illumination devices to significantly improve the dark field imaging effect;
6. The rear mounted camera interface design ensures that camera accessories no longer interfere with visual observation (using 100% light, suitable for low light microscopic photography cameras).
7. Modular functional design facilitates system upgrades and enables polarization observation, dark field observation, and other functions;
