Classification and application of industrial microscopes
A microscope is a sign that human beings have entered the atomic age. It is an optical instrument composed of one or more lenses, an instrument that magnifies tiny objects so that they can be seen by the naked eye.
The following is the classification of industrial microscopes: first, stereo microscopes, which are mainly used for on-site inspections, and are widely used in PCB, liquid crystal and other industries. Secondly, the metallographic microscope is suitable for material analysis, etc. The steel and gold processing industry requires measuring microscopes, which are more used in microelectronics and fine processing industries.
1. Stereo Microscope
Stereo microscope is also called "solid microscope" and "stereo microscope". It has the following characteristics:
1. The left and right light beams in the binocular tube are not parallel, but have a certain angle - stereoscopic angle (generally 12 degrees - 15 degrees), so the imaging has a three-dimensional sense;
2. The image is upright, which is convenient for operation and dissection, because the prism under the eyepiece inverts the image;
3. Although the magnification is not as good as that of conventional microscopes, its working distance is very long
4. The depth of focus is large, which is convenient for observing the whole layer of the object under inspection.
5. Large diameter of field of view.
At present, the optical structure of the stereo mirror is: a common primary objective lens, the two light beams after imaging the object are separated by two sets of intermediate objective lenses—zoom lenses, and integrated into a single angle of view and then imaged through the respective eyepieces. Its magnification change is It is obtained by changing the distance between the middle mirror groups, so it is also called "continuous zoom stereo microscope". According to the requirements of the application, the current stereoscope can be equipped with a variety of optional accessories, such as fluorescence, photography, video, cold light source and so on.
2. Measuring microscope
The measuring microscope adopts transmission and reflection methods to measure the length and angle of the workpiece precisely. Especially suitable for electronic industry, mechanical finishing. It is used to measure the width of electronic circuits and the geometric dimensions of fine small workpieces, as well as other precision parts. Enhanced measuring microscopes are widely used in measurement rooms, production lines and scientific research departments.
The measuring microscope is equipped with a high-precision working platform, a high-precision digital display micrometer, and a camera imported from Japan. You can aim directly on the computer screen without aiming with human eyes, reducing human error. So as to ensure the high precision of the instrument, it is an ideal multi-purpose small precision measuring instrument.
The measuring microscope adopts a high-precision working platform and is equipped with a high-precision digital display micrometer head. The operation is convenient and the reliability is strong. The magnification of the instrument is high. In addition to the movement of the X and Y coordinates, the worktable can also be rotated 360°, and can also be used to measure the Z coordinate in the height direction. In addition to the transmission and reflection lighting, the measuring microscope lighting system can also be used for oblique lighting.
3. Metallographic microscope
Metallographic microscope is mainly used to identify and analyze the internal structure of metals. It is an important instrument for metallographic research and key equipment for industrial departments to identify product quality. The instrument is equipped with a camera device that can capture metallographic images and analyze them. Maps can be measured and analyzed, and images can be edited, output, stored, and managed.
Metallographic microscopes are still the most commonly used instruments in routine inspection and research work due to their ease of operation, large field of view, and relatively low price.
