Metallographic microscope DM100

Introduction to Metallographic Microscope DM100
The metallographic microscope DM100 (bright and dark field reflection and transmission) is a multi-purpose optical instrument for industrial inspection. It is equipped with a bright/dark field objective lens, a large field eyepiece, and a polarizing observation device. The reflection and transmission illumination adopts the "Kohler" illumination system, and the field of view is clear. It can be used for the inspection of semiconductor silicon chips, LCD substrates, circuit boards, solid powders, and various other transparent or opaque industrial samples. It is an ideal instrument for research in biology, metallurgy, mineralogy, precision engineering, electronic engineering, and other fields.

Professional quantitative metallographic image analysis system for 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, statistics, and output of graphic and textual reports on decarburization layer, carburizing layer measurement, and surface coating thickness measurement.

Characteristics of the DM100 metallographic microscope
1. A dream of embarrassment, beans, and low officials? 2. Long working distance bright/dark field flat field objective lens, with a large and clear field of view.
3. Wide angle flat field eyepiece: field of view diameter of Ø 22mm.
4. Coarse micro motion coaxial focusing mechanism, adjustable coarse motion elasticity, with limit locking device, micro motion grid value: 2 μ m.
5. Built in switchable polarization observation device, polarizer? Rotate 60 degrees.
6. The upper light source adopts a flip type 12V50W halogen light box, which is safe and convenient to replace the lamp cannon. The lower light source adopts a 12V30W halogen lamp and is equipped with a heat sink.
7. The three eyepiece tube can freely switch between visual observation and microscopic photography, and can be illuminated 100% during photography, making it suitable for dark field microscopic image shooting.
