Difference between a metallurgical microscope and a stereoscopic microscope
Sound card rack and zoom organisation
1, metallurgical microscope sound card rack is generally very large, but because the metallurgical microscope is to do high-magnification testing with, it can put the specimen specifications are generally smaller, and the general provisions of the specimen surface layer is relatively flat, must be made of samples polished polished polished etching, this point on the inverted metallurgical microscope other than, although it must also be made of samples, but it is almost no limit to the specifications of the specimen, a good inverted metallurgical microscope can be placed on the roughly A good inverted metallographic microscope can hold about 10kg of specimens. In addition to the orthostatic metallographic microscope zoom organisation is to adjust the goniometer (there are very few orthostatic optical microscopes and measuring microscopes is to use a unique accessory to adjust the objective lens), inverted metallographic zoom organisation is to adjust the objective lens
2, body view microscope sound card rack specifications are generally smaller, but if the mutual cooperation of large-capacity moving sound card rack, it can check the specimen of different specifications and sizes, including the immediate inspection of the production line of goods, so it is a very low specimen provisions, and do not have to make professional sample, only need to make a sample of the surface about the flat can be. Because of the body rear view mirror is lighter, the body microscope zoom method is generally all the adjustment of all the light path server.
Stereo optical microscope
Enlargement of magnification
1, metallurgical microscope objective lens magnification in 1.25 times more than 100 times the following, the eyepiece magnification in the 10X to 20X in the middle, thus, the total magnification of metallurgical microscope in the middle of 12.5X to 2000 times.
2, the magnification of the stereo microscope is quite different, if it is a general test with the stereo microscope, the magnification is generally in the middle of 0.5 times to 100 times, if it is a scientific research level of optical microscope, in the enhancement of the quality of the electronic optics at the same time, the magnification of the magnification of the magnification of the up and down to 200 times to 400 times.
Illumination optical system software
1, metallurgical microscope is generally a professional refractive light illumination light path (due to the observation of the specimen is not fully transparent), and illumination light according to the half-reflective double light lens through the objective lens to irradiate the surface of the specimen, the reflective surface back home through the objective lens eyepieces and then to the human eye three-dimensional imaging, so the objective lens replaces the Jiumu illumination system software in the efficacy of the spotting mirror. From the basic principle, this type of lighting is attributed to the coaxial line lighting, that is, the illumination light and refracted light are in a main optical path.
2, stereo microscope general application of external light sources, there are side halogen headlamps scattered illumination, there are round LED lamps illumination, but this method of illumination is not coaxial illumination, their illumination light are scattered to the side, and the main optical axis has a certain angle of intersection, the basic principle and the metallurgical microscope dark-field illumination is somewhat like. In addition, a part of the body microscope is also a coaxial lighting source, but the body of the rear-view mirror coaxial lighting has certain limitations, if the design programme is not reasonable will cause flare, which must be coupled with a unique accessory or spectacle lenses to give the clearance
