The AELAB Metallurgical Microscope AE-MMT300/500 is designed for high-precision observation of metal and alloy microstructures. Featuring bright and dark field objectives, wide-view eyepieces, and robust illumination options, it delivers accurate, reliable results for metallurgy, materials science, and quality control applications.
A metallurgical microscope is designed for examining the microstructure of metals and other solid materials. It uses reflected light to illuminate the surface of opaque specimens, allowing for detailed observation of features like grain boundaries, phases, and inclusions. This type of microscope is essential in materials science, metallurgy, and quality control to assess the properties and quality of metals and alloys.
Features
Light distribution (both): 100: 0(100% for eyepiece)
80:20(80% for trinocular head and 20% for eyepiece)
The AELAB Metallurgical Microscope uses reflected light microscopy, projecting light onto the sample surface and capturing reflected beams through high-quality objectives. This allows researchers to observe grain boundaries, inclusions, and phase structures without the need for thin-section preparation. Bright field mode reveals general structures, while dark field enhances contrast for fine details.
High-resolution bright & dark field observation
Wide field eyepieces (22mm) for comfortable long-term viewing
