Models of Metallurgical Microscope

Labtron Metallurgical Microscope is specialized to provide detailed analysis of microstructure of metals and other materials at high magnification. They are equipped with mechanical stage to securely hold and maneuver samples during analysis. Their eyepieces often include reticles for accurate measurement of features within unit. They utilize polarizing filters to analyze anisotropic components and observe optical phenomena in metals. Our Metallurgical Microscope is versatile for weld quality assessment, grain size measurement, and heat treatment evaluation.
