Metallographic microscope is an important optical instrument for analyzing the metallographic structure of metal materials. Metallography mainly refers to the branch of materials science that analyzes, studies and characterizes the microstructure, low magnification structure and fracture structure o […]
For a separate eyepiece, when you place the object where it can image, it will form a positive image or a reverse image. We have learned that the convex lens can be used as a magnifying glass. When we place the object at a point within the focal point of the convex lens, the virtual image formed by […]
Electron microscopes and optical microscopes are optical instruments that are widely used in many fields. Electron microscope is a large-scale instrument that takes the electron beam as the illumination source, transmits or reflects the sample through the electron flow and multi-stage magnification […]
With the development of high technology and the popularization of electronic products, the group’s eyesight is constantly declining. The rate of myopia in children is increasing year by year, and the degree of myopia in adults is also increasing year by year. The main reason for this phenomeno […]
1. First, find out what kind of optical instrument is suitable for the product you are testing. If you only need to observe the appearance of the product and the optical magnification is about 100x, you can choose a stereo microscope or a video microscope; if you need to analyze the product structur […]
For an optical component in a metallographic microscope, some mechanical components, such as eyepieces, objective lenses, photographic installations, etc., must be stored separately for storage requirements, and they need to be installed and disassembled when using the microscope. Installation steps […]
The upright metallographic microscope includes two illumination systems, transmission and reflection, which are two light sources up and down. The upright metallographic microscope mainly observes cermets, electronic chips, printed circuits, LCD substrates, films, fibers, granular objects, The struc […]
Adjust the viewing/photographing switch knob on the metallographic microscope to the phot position, convert the information observed in the metallographic microscope to the video interface and camera, turn on the computer, start the image analysis software, and view the real-time image in the metall […]
The focusing mechanism of the metallographic microscope is mainly composed of two parts: coarse focusing and fine focusing. The coarse focus adjustment mechanism is used for fast focus adjustment during microscopic operation. The micro-moving focusing mechanism is used for further cutting. In the pr […]
1. Common faults of metallographic microscope: The image of metallographic microscope is partially ambiguous, and the visual newness is not good, such as the image is not obvious, the contrast is not good, and the details are unclear. Treatment method: the sample may not be flat, and the sample need […]
