Technical Info
| 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. |
| The tube lens focal length is the focal length from the tube lens to the intermediate image plane of the design of infinite microscope, and its typical ranging is from 160 to 200 mm, depending on different manufacturers. |
| 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. |
| 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. |
| 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. |
| Static electricity is a charge that is at static or non-flowing state, and static electricity is formed when charges accumulate on an object or surface. Static electricity can cause malfunction or mis-opeartion of electronic equipment, resulting in electromagnetic interference. In the electronics industry, static electricity can break down integrated circuits and precision electronic components, causing components to age, and can also absorb dust, causing contamination of integrated circuits and semiconductor components, and reducing production yield. In the plastics industry, static electricity can cause film or membrane not wining up uniformly, film and CD plastic discs contaminated with dust, thereby affecting quality. In industrial production, especially in electronic production and processing and inflammable and explosive production sites, electrostatic protection should be taken seriously. ESD means "electro-static discharge." For the methods of ESD treatment with respect to microscope and components, electrical conductivity of the metal should be utilized on the one hand, and on the other hand, electrostatic materials, electrostatic coating and other methods of treatment should be adopted to solve the electrostatic problem. Electrostatic coating is to apply coat that can prevent static electricity. It has electrostatic discharge, dust-proof, mildew-proof, wear-resistant, acid and alkali resistance and other characteristics. The surface of the coating does not generate static electricity or the static electricity is discharged to the safe place through the conductor row. On some components, electrostatic materials may be applied, such as the microscope knob handle, insulation mat, septum, microscope cover etc. |
| 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. |
