Žingsniai už naudojimas an optinis mikroskopas

（1） Upright microscope

1. Vieta jūsų dešinė ranka to hold the mirror arm and your left hand to support the mirror base, keeping the mirror body upright. The desktop should be clean and stable, and a window facing or well lit area should be selected. The single tube is usual placed on the left side, 3-4} centimetr away from the table edge.

2. Švarus ir apžiūrėti the mikroskopas for any defects and cleanliness. The mechanical part of the mirror body can be wiped with a clean soft cloth. The lens should be wiped with lens wipeping paper. If there is glue color glue' or dirt, a small amount of xylene can be used to clean it.

3. Pakelti the aiming objektyvas vamzdelis to a atstumas of 1-2} centimetrai nuo the stage, and align the low-power lens with the light hole. Adjust the aperture and reflector. When the light is strong, use a flat mirror. When the light is weak, use a concave mirror. The reflector should be rotated with both hands. If a mikroskop with a light source is used, the secondary step can be praleista, but a rankenėlė for reguliavimas the brightness is required.

4. Install the specimen and place the slide on the stage, užtikrinant that the side with the cover slide is face ups. Fix the glass slide with a spring clip and rotate the knob of the platform shifter to align the material to be observed with the center of the light hole.

5. Kai fokusavimas, pirmas pasukimas the coarse fokusavimas rankenėlė to lėtai žemiau the lens barrel, ir atsargiai stebėkite from the side till the objective lens is close to the glass specimen. Then, observe with the left eye from the eyepiece, and rotate the coarse focusing knob with the left hand to lift the lens barrel till the specimen image is clear visible. Then, use the fine focusing knob to adjust atgal į aiškumą. Operacija pastaba: Do ne fokusas tiesiogiai po a didelės galios objektyvas; Kada the objektyvas vamzdelis nusileidimas, the distance between the lens tube and the specimen should be observed from the side; To understand the critical value of object distance. If a binocular mikroskop is used, if there is a difference in the binocular vision of the observer, the reliable vision adjustment circle should be used for adjustment. In papildymas, the du cilindrai gali būti santykinai transliacija to prisitaikyti į atstumą tarp the operatorius's akys.

6. If a single tube mikroskopas is used for observation, the two eyes should naturally open, the left eye should observe the specimen, the right eye should observe the recording and drawing, and the left hand should adjust the focal length to make the object clear and move the specimen's field of view. Record and draw with the right hand. Metu mikroskopinis tyrimas, the specimen should be moved in a certain direction und the whole specimen is observed, so as not to miss or repeat the examination. Reguliavimas of light intensity: In general, the light should be strong for stained specimens, and weak for colorless or unstained specimens; The light should be weak when observing with a low-power lens, and strong when observing with observing with a high-power lens. In papildymas prie reguliavimas the reflektorius arba šviesa šaltinis, the reguliavimas of the iris diafragma is taip pat labai svarbu.

1) Kai stebėjimas bet koks mėginys po a mažos galios mikroskopas, it is būtina to pirmas naudojimas a mažos galios mikroskopas nes jo laukas išvaizdo is didelis, darymas it easy to aptikti the target and determine the area to be observed.

2) When observing with a high-power lens from a low-power lens to a high-power lens, just slightly adjust the fine focusing knob to make the object image clear. Do not use a coarse focusing knob when using a high-power lens, as it can easily crush the cover glass and damage the lens. When rotating the objective lens converter, it is not advisable to directly push the objective lens with your fingers. This can easily cause the optical axis of the objective lens to deviate, causing uneven force on the converter threads and damage, resulting in the converter being scrapped.

(3) To observe with an oil mirror, first use a low-power or high-power lens to move the object to the center of the field of view, and then change the oil mirror for observation. Before observing with an oil mirror, the brightness of the microscope should be adjusted to * bright and the aperture should be fully opened. When using an oil lens, first add a drop of cedar oil (lens oil) to the cover glass, then lower the lens tube and carefully observe from the side until the oil lens is immersed in cedar oil and close to the glass specimen. Then observe with an eyepiece and use a fine focusing knob to lift the lens tube until the focal segment of the specimen is clearly visible, and stop and adjust it clearly. Add an appropriate amount of cedar oil dropwise. After using the oil mirror, it is necessary to wipe off the cedar oil with xylene dipped in lens wiping paper, and then use dry lens wiping paper to wipe off excess xylene.
