Some experience using the interference microscope
Surface image, you should adjust the rotary table Zhi workpiece surface up or down, eyepiece field of view can appear as the workpiece surface, see Zhou l. Then the orange light color is best. 0} li: e,[link widoczny dla zalogowanych], does not appear to find interference with the workpiece surface is like looking for interference with a critical first step. Gobo wheel spin operator will come back to the standard microscope light path to get through, and then slowly turn the adjustable bench spine. If the eyepiece field of view does not appear in the interference fringes, the first round to check the position of shading board operator: second check whether the light filters into the optical path; re-adjust the standard of chronic back and forth rotating mirror and the microscope objective (in the standard lens side) the distance between the hand wheel, adjust the standard microscope objective lens and the distance between the standard mirror surface accuracy in the imaging field of view in the eyepiece. At the same time elevating rotary table with the fine-tuning until the eyepiece field of view are interference fringes, ran to seek the source filter removed from the road to color interference fringes can be observed standard mirror Mighty Pan F and - 'in the related with hand wheel adjustment is for the entire repair equipment used in normal circumstances throw cutting rotation. - Basket,[link widoczny dla zalogowanych], interference with filament light source is not clear, as such groups are not the focus of the collimator on the uneven field illumination is the main reason for interfering with a lack of clarity. Stupid way to check is: quill micrometer head under the lens. Received from the eyepiece tube filament was observed, as if the light Simeng around a few vague and there. Clamor to further adjust the switch position of the lamp so that light sleet Jiang compliance sings i j} of the focus, and then loaded micrometer head shots, and then the table from the rotation for years, if the sun is also] the amount of technology-eg916 Xu magnification to see clearly like filament. Then the DUT back on the table, from the eyepiece field of view can be found in the intensive intervention more clearly. VII, interference with or without light. Interference with light and the aperture stop is not relevant, followed by the coke still have not transferred to the best location. Fine-tune the focus back to the dig when the interference with the regulation with the aperture can become bright. Few, light shower white color selection and look forward to a better compared to monochromatic phase with thousands of, interference with the more convenient to find. Wavelength monochromatic light has a definite value can provide 【high measurement accuracy, it is generally monochrome green (the photographs Lu orange light), for the processing of relatively low surface finish without the rules of the measured surface, the use of monochromatic light is not easy to observe and measurements. Bad white good. ,,. i nine, interference with the choice of fringe width and direction of rotation and direction of the width of interference fringes with hand wheel adjustment, interference can change the width and direction of striped. Interference with the direction of stripes should be vertical to the direction of the workpiece surface machining marks,[link widoczny dla zalogowanych], shown in Figure 2. i head 2. Muscle observed in the eyepiece field of view, the width of interference fringe spacing should be 3 of a millimeter. For R> 0.16 p, is a system of surface, slightly larger than the eyepiece field of general basic degree f. Interference fringes that are inclusive and trough to peak for the 5 R> 0.02-0. O1 of the measured surface, the eyepiece field of view than about 3 to 4 times as large f, ie inclusive of 15 - 20 trough to peak interference fringes, so easy to observe. Ten, the correct reading intervention should be in the eyepiece field of view with the central, rotating micrometer head shot, and adjust the eyepiece micro-guillotine drum head, so that the cross-line eyepiece micrometer horizontal line parallel to the direction and the interference fringes, and it is striped interference location in question, not aimed at its edges (see Figure 3). When measuring the length of the length should contain several basic averaged. Embroidery: J a Ⅳ, I circle a muscle 3 November, the placement of parts and equipment for measuring the quality of the small pieces can be placed directly on the table, the table facing the lens under test. The quality of the larger measured. Parts, not on the table rotation, can be placed in the self-adjustable supporting bracket. Domestic 61-4 type interference microscope, small size, light weight, can take advantage of home-made adjustable bracket upside down in the test surface,[link widoczny dla zalogowanych], or directly measured by inverted in the set to measure the surface characteristics. X =, equipment maintenance in addition to general maintenance and repair, the use of dry fat coma microscope to the attention of vibration can be the base Xiadian to _ =. Mm thick rubber, the optical adjustment of the instrument to maintain a good state of a (on the next page 35.) . Effective figure 2) rounding down grub about women is even retained a bit before the revision and the odd diagram shown in Figure 1 and Figure 2. Figure 1, the last digit of the proposed amendment is about 'L3'5, 7 and 9, were revised to be approximately O, 4,4,8 and 8. Figure 2, the value to be rounding the last digit is l, 3,[link widoczny dla zalogowanych],5, {Pi 7 and 9, were revised to be about 2,2, q, 6 and 10. In my opinion, \Test and test results for the numerical rounding, can play the role of a unified and standardized. For the test and testers. . The rounding method is simple, clear and easy to understand so as to quickly grasp and apply.
