Inverted bright dark field metallographic microscopeSpecific information of 4XG:
1. Purpose
The 4XG series research-oriented inverted bright dark field metallographic microscope adopts the functional design concept of excellent infinite distance optical system, wide-angle large eyepiece, and infinite long working distance flat field objective lens, which can easily upgrade the system to achieve polarization observation, dark field observation and other functions. The compact and stable high rigidity body not only has the same functions as a research grade large-scale metallographic microscope, but also fully reflects the anti vibration requirements of microscope operation. Ideal design that meets ergonomic requirements, making operation more convenient, comfortable, and spacious. Suitable for microscopic observation of metallographic structure and surface morphology, it is an ideal instrument for research in metallurgy, mineralogy, and precision engineering. Microscopic photography and image analysis systems can be configured to meet most of the higher requirements for physical and chemical analysis and inspection.
2、 System composition
The research-oriented inverted bright dark field metallographic microscope system combines traditional optical microscopes with computers (digital cameras) through photoelectric conversion. It can not only perform microscopic observations on the eyepiece, but also observe real-time dynamic images on the computer (digital camera) display screen, and edit, save, and print the required images.
