Upright metallographic microscope BM-230D series with polarizing device, three eye falling light upright metallographic microscope
Usage characteristics
Vertical metallographic microscope, with observation facing upwards, suitable for observing, researching, and analyzing surface targets within a specific or wide range. Widely used in the IT, PCB, and micro particle, wire, fiber, surface coating industries of the electronics industry, as well as in the detection, research, and analysis of material metallographic structures. Widely used in factories, laboratories, teaching and research fields.
The coaxial illumination system with polarizing device provides clear images and good contrast, suitable for observing and photographing various complex specimens.
The coaxial longitudinal and transverse moving stage and built-in multiple color filter switching make operation convenient.
The lifting and focusing system is equipped with a limit device, which can avoid collision between the sample and the objective lens, and does not require repeated focusing during large-scale testing
