CDM-920Laboratory inverted metallographic microscope
一、Instrument use
The CDM-920 is ideally designed for ergonomics, making operation easier and more comfortable. It is suitable for microscopic observation of metallographic structure and surface morphology. It is an ideal instrument for metallurgy, mineralogy and precision engineering research. Also suitable for the electronics, metallurgy, chemical and instrumentation industries to observe transparent, translucent, opaque materials such as metals, ceramics, manifolds, printed circuit boards, liquid crystal panels, films, fibers, coatings and other non-metallic materials. It is suitable for observation and analysis by medicine, agriculture, forestry, public security, schools and scientific research departments.
二、introduction
The CDM-920 series of metallographic microscopes have high-performance optical systems, simple operation, innovative technology, perfect functions and good stability to meet your application needs now and in the future. This product has two camera interfaces that can connect two computers (digital cameras) at the same time to share images. Flexible upgrades, such as DIC observations.

四、 advantage;
This machine has bright field, dark field and polarized light function. Customers can upgrade and add DIC differential interference function if necessary. The optical system is excellent, the working distance of the objective lens is large, and it is convenient to operate. The objective lens adopts semi-apochromatic infinity objective lens, and the image is clearer. It is a fine machine in metallographic microscope.
Equipped with energy-saving system, the boot is not tried for a long time, the light source is automatically dimmed, the objective lens is multiplied, and the microscope has a zoom digital display, which is convenient for knowing the multiple
Observation system: hinged binocular viewing tube, 30° tilt, no need to look down or look up for a long time during operation, so that the operator's shoulder is effectively released. The field wide-angle eyepiece has a field of view of up to 22 mm in diameter, which makes the eyepiece field wider and more comfortable, with a rubber eye patch.
Mechanical stage: mechanical moving platform, built-in rotatable circular stage plate, shaped viewing window set in the board is suitable for microscopic observation of different specifications of samples, can be rotated circularly for polarized observation The platen is used to meet the requirements of polarized light inspection.
Lighting system: With the Corolla lighting method, the aperture diaphragm and the market light bar can be adjusted by the dial to adjust the aperture comfort. The optional polarizer can adjust the polarization angle 360° to observe microscopic images in different polarization states. Optional DIC differential interference chip to quickly upgrade product system functions.
Dark field illumination: equipped with high-quality light and dark field of view and dark field illumination device to effectively eliminate the harmful light of the illumination system, so that the imaging effect of the dark field is significantly improved.
Photographic camera observation: The rear-mounted camera interface design makes the camera accessories no longer interfere with visual observation. With 100% pass light, it is suitable for low-light photomicrography camera. It is equipped with a 12-megapixel 1/1.7” large-format camera. The image is clearer and more vivid.
