Product details
Inverted metallographic microscopeCMM-20
1、 Purpose:
The CMM-20E/CMM-20Z series is an inverted metallographic microscope equipped with a flat field objective lens and a large field eyepiece, providing clear images, good contrast, and complete optical magnification. Inverted metallographic microscope is mainly used for identifying and analyzing the internal structure and structure of metals, as well as for identifying the quality of castings; Inspection of raw materials or analysis of metallographic structure after material processing; Observe and analyze surface conditions such as spray coating and cracks. Inverted metallographic microscopes are widely used in laboratories of factories and mines, key laboratories of universities, and scientific research departments. Inverted metallographic microscopeCapable of editing, saving, and printing the required images.
2、 System Introduction
Inverted metallographic microscopeThe 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.
