1.Application and characteristics
4XB binocular-type inverted metallurgical microscope is used for the identification and analysis of various
metals and alloys of the organizational structure, the general microstructure of the research work for the material
after heat treatment. Microscope imaging is clear, of broad vision; the overall design is in line with the man-machine
functions, fit to being operated for a long time. Can be widely used in factories or laboratories for the identification
of casting quality. Raw material inspection or the treated material microstructure research and analysis work.
This is an inverted optical microscope, because the surface of the specimen was observed coincide with the table
surface, so it has nothing to do with the sample height, the use of convenience, the apparatus of compact structure,
elegant appearance, apparatus base supporting the larger, curved arm robust, low center of gravity so that the equipment
placed smooth and reliable, because of eyepiece with the support surface is tilted 45 degrees, so that the observation of comfort.
