Metallurgical MicroscopeClose Λ
| A metallurgical microscope is a microscope that uses incident illumination (also known as reflection light) to observe the metallurgical structure of the surface of a metal specimen and perform microscopic analysis. Metallurgical microscopic analysis is widely involved in the material microstructure, internal components, state imaging, and qualitative and quantitative analysis, including the quantitative and spatial distribution of the phase and tissue structure, composition, crystallization and sub-crystallization, non-metallic inclusions, and tissue defects of the materials etc. Metallurgical microscope is one of the important components of industrial microscope. In addition to observing metal surface, metallurgical microscope plays an important role in metal heat treatment and cold processing. It is no longer limited to metal research, as it is also widely applied in other opaque or translucent objects, including fibers, soils, minerals, crystals, ceramics, surface treatments, integrated circuits, LCD screens, and other industries. Modern Metallurgical microscope not only have good optical systems, but also combine optical microscope, photoelectric conversion technology, and computer image processing technology to easily observe metallurgical images and analyze and rate metallurgical maps. The quality of the image is the primary indicator of metallurgical microscope. Metallurgical microscope needs the basic conditions of optical imaging such as high brightness, high contrast, high resolution and good color reproduction. At the same time, due to the environment applied, the microscope needs to be solid and durable. Metallurgical microscope generally uses coaxial reflection light method. The illuminating light passes through a coaxial reflection illuminator, after rotating a 90 degree angle, it is irradiated vertically (or nearly vertically) to the surface of the object to be observed, and then reflected back into the eyepiece through the objective lens. Notes on the Use of Metallurgical Microscope: When the observed metal surface is too rough, due to the diffusing effect of the incident light, the microscope cannot observe its internal structure, grinding and polishing of the surface of the metal sample must be carried out. However, during the process, no tissue structural change should occur on the surface; when some metal structures have a particularly strong surface reflection, it is necessary to use a certain reagent for corrosion treatment, dissolve some components, and thus see the morphology of the tissue. Metallurgical microscope are complex in function and diverse in components, and often large-scale metallurgical microscope are modular and require self-installation and commissioning. Be sure to read the operating manual first and carefully check the completeness of the components. Prior to installation and use, installation and adjustment of location of components are required. In particular, the positional adjustment of the light source in the coaxial reflection illuminator has a very big influence on the brightness and uniformity of the imaging illumination. For more information on the use of metallurgical microscopes, please refer to the Biological Microscope Biomicroscope on the BoliOptics website. |
InfiniteClose Λ
| Microscopes and components have two types of optical path design structures. One type is finite optical structural design, in which light passing through the objective lens is directed at the intermediate image plane (located in the front focal plane of the eyepiece) and converges at that point. The finite structure is an integrated design, with a compact structure, and it is a kind of economical microscope. Another type is infinite optical structural design, in which the light between the tube lens after passing the objective lens becomes "parallel light". Within this distance, various kinds of optical components necessary such as beam splitters or optical filters call be added, and at the same time, this kind of design has better imaging results. As the design is modular, it is also called modular microscope. The modular structure facilitates the addition of different imaging and lighting accessories in the middle of the system as required. The main components of infinite and finite, especially objective lens, are usually not interchangeable for use, and even if they can be imaged, the image quality will also have some defects. The separative two-objective lens structure of the dual-light path of stereo microscope (SZ/FS microscope) is also known as Greenough. Parallel optical microscope uses a parallel structure (PZ microscope), which is different from the separative two-object lens structure, and because its objective lens is one and the same, it is therefore also known as the CMO common main objective. |
System Optical MagnificationClose Λ
| The magnification of the objective lens refers to the lateral magnification, it is the ratio of the image to the real size after the original image is magnified by the instrument. This multiple refers to the length or width of the magnified object. System optical magnification is the product of the eyepiece and the objective lens (objective lens zoom set) of the optical imaging part within the system. Optical magnification = eyepiece multiple X objective lens/objective lens set The maximum optical magnification of the microscope depends on the wavelength of the light to which the object is illuminated. The size of the object that can be observed must be greater than the wavelength of the light. Otherwise, the light cannot be reflected or transmitted, or recognized by the human eye. The shortest wavelength of ultraviolet light is 0.2 microns, so the resolution of the optical microscope in the visible range does not exceed 0.2 microns, or 200 nanometers. This size is converted to the magnification of the microscope, and it is the optical magnification of 2000X. Usually, the compound microscope can achieve 100X objective lens, the eyepiece is 20X, and the magnification can reach 2000X. If it is bigger, it will be called "invalid magnification", that is, the image is large, but the resolution is no longer increased, and no more details and information can be seen. |
Trinocular Optical MagnificationClose Λ
| When the instrument is conducting electronic image magnification and observation through a camera or the like, the optically magnified portion may not be the optical path that passes through the "eyepiece-objective lens" of the instrument, at this time, the calculation method of the magnification is related to the third-party photo eyepiece passed. The trinocular optical magnification is equal to the multiplier product of objective lens (objective lens set) and the photo eyepiece Trinocular optical magnification = objective lens X photo eyepiece |
Total MagnificationClose Λ
| Total magnification is the magnification of the observed object finally obtained by the instrument. This magnification is often the product of the optical magnification and the electronic magnification. When it is only optically magnified, the total magnification will be the optical magnification. Total magnification = optical magnification X electronic magnification Total magnification = (objective X photo eyepiece) X (display size / camera sensor target ) |
System Field of ViewClose Λ
| Field of View, is also called FOV. The field of view, or FOV, refers to the size of the object plane (i.e., the plane of the point of the observed object perpendicular to the optical axis), or of its conjugate plane (i.e., object to primary image distance), represented by a line value. System field of view is the size of the actual diameter of the image of the terminal display device of the instrument, such as the size of the image in the eyepiece or in the display. Field of view number refers to the diameter of the field diaphragm of the objective lens, or the diameter of the image plane formed by the field diaphragm. Field of view number of objective lens = field of view number of eyepiece / (objective magnification / mechanical tube length) Large field of view makes it easy to observe the full view and more range of the observed object, but the field of view (FOV) is inversely proportional to the magnification and inversely proportional to the resolution, that is, the larger the field of view, the smaller the magnification, and also the lower the resolution of the object to be observed. There are usually two ways to increase the field of view, one is to replace with an objective lens of a smaller multiple, or to replace with an eyepiece of a smaller multiple. |
Illumination BaseClose Λ
| Illumination base is a modular light source component, suitable for microscope stand base that has no light source of itself, and it is usually dedicated components supporting some stands. Illumination base typically includes at least one bottom lighting, and there are also illumination base that includes the circuit portion of the upper light source. |
Coaxial Coarse/Fine FocusClose Λ
| Focus mechanism, the coarse / fine focus knobs are in a coaxial center position, they are connected together by a gear reduction mechanism, which can be coarse/ fine focus adjusted at any time during the entire stroke. Generally, the coarse focus diameter is relatively big, which is inside close to the body of the microscope, and the fine focus diameter is relatively small, which is outside of the body of the microscope. Coarse focus adjustment is used to quickly move to find the image, and the fine focus adjustment is used to finely adjust the clarity of the image. Generally, the minimum read value of the fine focus adjustment can be accurate to 1 micron, and single circle can reach a stroke of 0.1 mm. Mechanical fine focus plays a very important role in the accuracy of the microscope resolution. If the fine focus accuracy is not enough, or cannot be stabilized at the sharpest focusing position, the image will be out of focus and become blurred. The tightness of coarse focus is generally adjustable. Generally, on one side of the knob (usually on the right side), there is a textured knob on the inside of the coarse knob, which is tightened if rotated clockwise; and loosened if rotated counterclockwise. In the process of focusing, direct focusing should not be on the objective of high magnification; instead, find the object of low magnification first, and gradually adjust to high magnification. Usually, the coarse focus knob is rotated first, and when the objective lens is gradually lowered or the platform is gradually rising, find the object, and then adjust with the fine focus, until the object image in the field of view is clear. Generally, when changing from low magnification to high magnification objective, one only need to slightly adjust the fine focus knob to make the object image clear. During the process, the distance between the objective and the specimen should be observed from the side, to understand the critical value of the object distance between the lens and the specimen. When using a high magnification objective, since the distance between the objective and the specimen is very close, after the image is found, the coarse focus knob cannot generally be used, and the fine focus knob can only be used to avoid excessive distance of movement, damaging the objective and the slide or specimen. By using the characteristics of the fine focus, the height or thickness of the observed object can be roughly measured under the microscope, such as measuring the thickness of the cell or tissue, the thickness of the cover glass, and the thickness of small objects that cannot be measured by various conventional measuring instruments. Method of measurement: place the object to be measured at the center of the field of view of the stage. After the image is clearly focused, try to use the highest magnification objective as much as possible, and align the adapter of the top feature point of the object to be measured. After adjusting clear, record the position of scale of the fine focus knob. Then, move the objective down to the adapter of the lowest feature point of the object to be measured, and record the position of scale of the fine focus knob. Then, according to the above fine focus, record the number of rounds of movement, and based on the parameters of conversion of each round into stroke (see the microscope fine focus knob parameters), the number of rounds is converted into the total stroke, which is the height of the object to be measured. If it is repeated a few times for average, a more accurate measurement can be obtained. |
Focus LimitedClose Λ
| Mostly, at the junction of the compound microscope platform and the body, there is a longitudinal limit mechanism. When the limit mechanism is locked, the platform is prevented from moving up and colliding with the microscope objective, thereby damaging the specimen or destroying the lens. On its first use, use one specimen, applying 100X or the highest magnification lens, carefully find the clearest image, then lock the axial limit mechanism down, the focus mechanism will remember this position. When the focus is adjusted again to reach this position in the future, it will not go up again, and the platform or specimen will not touch the lens. |
Focusing Knob Tightness AdjustableClose Λ
| Different microscope bodies, different human operations, and different requirements for observation and operation, all require adjustment of the pre-tightening force of the stand that support microscope body. Facing the stand just right, use both hands to reverse the force to adjust the tightness. (face the knob of one side just right, clockwise is to tighten, counterclockwise is to loosen) In general, after long-time use, the knob will be loose, and adjustment is necessary. |
Kohler IlluminationClose Λ
| Kohler illumination: is a secondary imaging illumination that overcomes the shortcoming of direct illumination of critical illumination. After the filament of the light source passes through the condenser and the variable field diaphragm, the filament image falls for the first time in the condenser aperture diaphragm, the condenser forms a second image at the back focus plane position there, so that there is no filament image at the plane of the object to be observed, and the illumination becomes uniform. During observation, by changing the size of the condenser aperture diaphragm, the light source fills in the entrance pupil of the objective lens, and the numerical aperture of the condenser is matched with the numerical aperture of the objective lens. At the same time, the condenser images the field diaphragm at the plane of the observed object, and the illumination range is controlled by the size of the field diaphragm. Since the thermal focus of Kohler illumination is not at the plane of the object to be observed, the object to be observed will not be damaged even if it is irradiated for a long time. |
PackagingClose Λ
| After unpacking, carefully inspect the various random accessories and parts in the package to avoid omissions. In order to save space and ensure safety of components, some components will be placed outside the inner packaging box, so be careful of their inspection. For special packaging, it is generally after opening the box, all packaging boxes, protective foam, plastic bags should be kept for a period of time. If there is a problem during the return period, you can return or exchange the original. After the return period (usually 10-30 days, according to the manufacturer’s Instruction of Terms of Service), these packaging boxes may be disposed of if there is no problem. |
