Donghua special-grade upright transmission and reflection metallographic microscope

', upright transmission-reflection metallographic microscope
Usage characteristics
The upright reflection/transmission microscope adopts a transmission-reflection illumination system, equipped with a plan achromatic objective lens and a wide-field eyepiece. The optical system provides clear imaging and a wide field of view. broad.
Used to observe and measure various microstructures, such as metals, petrography, ceramics, integrated blocks, printed circuit boards, liquid crystal panels, films, fibers, coatings, particle sizes, etc.
Suitable for metallurgy, electronics, chemicals, building materials, mining and other industries, it is mainly used to identify and analyze the internal structure and organization of materials, and is an important tool for microscopic observation and measurement.
Using a combination of transflective and two-way light to illuminate the object, coupled with a polarizing device, it is especially suitable for the inspection and analysis of petrographic facies.
