What are the three steps to using a microscope, and what are the steps to using a microscope?

Precautions for use of the microscope and its use.

Lens collection and placement.

Light. Observe.

The steps to use the microscope are:

1. Take and place the lens Hold the mirror arm with your right hand, hold the lens holder with your left hand, place the microscope on the experimental table, and install the eyepiece and objective lens slightly to the left;

2. Align the light Rotate the converter to align the low-magnification objective lens with the clear aperture Align a large aperture with the clear aperture The left eye is fixed in the eyepiece, and the right eye is opened, so that it is convenient to observe the drawing in the future Turn the reflector to see the bright field of vision

3. Observation Put the glass slide to be observed on the stage, press it with a tablet clamp, and the specimen should be facing the light aperture Rotate the coarse collimation spiral to make the lens barrel slowly descend until the objective lens is close to the glass slide Look at the objective lens so that the objective lens does not touch the glass specimen The left eye looks into the eyepiece, and at the same time rotates the coarse collimation spiral in the opposite direction, so that the lens barrel rises slowly until the image is clearly seen, and then slightly rotates the fine collimation spiral to make the image of the object seen more clearly

Therefore, the answer is: 1. Take the lens and place it Hold the mirror arm with your right hand, hold the lens holder with your left hand, put the microscope on the laboratory table, and install the eyepiece and objective lens slightly to the left;

2. Align the light Rotate the converter to align the low-magnification objective lens with the clear aperture Align a large aperture with the clear aperture The left eye is fixed in the eyepiece, and the right eye is opened, so that it is convenient to observe the drawing in the future Turn the reflector to see the bright field of vision

3. Observation Put the glass slide to be observed on the stage, press it with a tablet clamp, and the specimen should be facing the light aperture Rotate the coarse collimation spiral to make the lens barrel slowly descend until the objective lens is close to the glass slide Look at the objective lens so that the objective lens does not touch the glass specimen The left eye looks into the eyepiece, and at the same time rotates the coarse collimation spiral in the opposite direction, so that the lens barrel rises slowly until the image is clearly seen, and then slightly rotates the fine collimation spiral to make the image of the object seen more clearly

1. Place the microscope: hold the mirror arm with your right hand, hold the lens base with your left hand, put the microscope on the experimental table, slightly left about 7 cm from the edge, and place the eyepiece and objective lens.

2. Optical 1. Rotation converter.

Align the low-magnification objective with the clear aperture and keep the front of the objective 2 cm away from the stage.

2. Align a larger aperture at the light aperture. The left eye is fixed on the eyepiece, the right eye is open, and the reflector is turned.

Allows light to be reflected into the lens barrel through the aperture. until you see a brighter field of view.

3. Place the slices.

1. Place the slide specimen to be observed on the stage and press it with a tablet clamp, and the specimen should be facing the center of the light hole.

4. Observation. 1. Turn the coarse collimation spiral to slowly lower the lens barrel and look at the side until the objective lens approaches the slide specimen, so as not to touch the slide specimen.

2. Look into the eyepiece with the left eyepiece, and at the same time rotate the coarse quasifocal spiral in the opposite direction to make the lens barrel slowly rise and straight.

Until you can see the image clearly. Then turn the fine collimation spiral slightly to make the image of the object seen more clearly.

Fifth, close the camera. 1. Remove the slices.

2. Rotate the converter to align the low-magnification objective or the place without the objective lens with the clear hole, lower the lens barrel, and approach the stage.

3. The reflector is placed vertically.

The steps to use the microscope are as follows:

1) First of all, under the low magnification, aim at the light source and adjust the reflector to be the brightest in the field of view.

(2) Then place the specimen slide in the stage.

(3) Then lower the lens barrel to the slide as soon as possible.

(4) Continue to lower the collector or adjust the aperture down.

(5) Slowly raise the lens barrel with coarse adjustment until you can see the specimen clearly.

(6) Finally, use a high magnification lens, magnify the aperture and ascend the light collector, and adjust the fine adjuster until you can see clearly.

1. Take the lens and place it; 2. Pair light; 3. Observation; 4. Focusing; 5. Observation under the vertical magnification of the smart crack; 6. Move the image of the object observed under the low magnification to the ** of the field of view; 7. Turn the converter, observe with a high magnification lens, and gently rotate the fine collimation spiral until you can see the image clearly.

The optical microscope is composed of an eyepiece, an objective lens, a coarse collimator, a fine collimator, a tablet clamp, a clear aperture, a light shield, a converter, a reflector, a stage, a mirror arm, a lens tube, a lens holder, a condenser, and an optical diaphragm.

A microscope is an optical instrument composed of a lens or a combination of several lenses, which is a sign that mankind has entered the atomic age. It is mainly used to magnify tiny objects and become instruments that can be seen by the human eye.

Microscopes: Optical microscopes and electron microscopes: The optical microscope was pioneered in 1590 by Janssen & Sons of the Netherlands. The current optical microscope can shoot the object 1600 times larger, and the limit of the front size of the resolution reaches 1 2 wavelength, and the length of the mechanical barrel of the domestic microscope is generally 160 mm.

Among them, the person who has made great contributions to the development of microscopes and microbiology is Leeuwenhoek, a Dutch national.
