(Summary description)Microscope is no stranger in our daily life. Maybe you are very familiar with its composition, but do you still remember its operation steps? Although we have relevant knowledge introduction in the textbook of junior high school, we can't remember it. Next, let's learn about it together!
First, take the mirror and place it
When we use the microscope, we must be careful, holding the arm with the right hand, and firmly dragging the base with the left hand. This is only the first step, and care must be taken to avoid damaging the microscope. Then put the microscope on the experimental platform, slightly to the left, and then you can install the eyepiece and objective lens.
Second, light
At this time, we need to slowly rotate the converter so that the low power objective lens is aligned with the through-hole. One thing to strictly follow the operating procedures of the microscope. At this time, we need to aim the left eye at the eyepiece, and the right eye can be opened. When we have finished observing, we can draw figures on the paper. You can also adjust the mirrors according to the brightness of the field of vision.
Third, observation
This is a crucial step. Of course, we should make preparations in advance and put the objects to be observed on the stage. Press firmly with the tablet. Then we have to slowly rotate the coarse focusing spiral to gradually lower the lens barrel. This distance depends on the distance between it and the carrier plate. As long as the distance is appropriate, the eye should also look at the objective lens. The next step is similar to this step. The left eye should look at the eyepiece, but it should be noted that it should be rotated in the opposite direction. Out of the focus spiral, let the lens tube slowly rise, appropriate rotation until the object is clear. Then turn the fine focusing spiral, which will make the image more clear.
The operation of microscope is actually very simple. As long as you look at the relevant knowledge, follow the above steps can quickly master this skill. It is very helpful for us to learn the operation steps of microscope and do some experiments. At the same time, it is also helpful for us to understand more microorganisms.
