Find out how to use the microscope!! Urgent!!

1 Hold the arm with your right hand and hold the base with your left hand.

2 Place the microscope on the bench, slightly to the left (the microscope is about 7 cm away from the edge of the bench). Attach the eyepiece and objective.

2. Alignment 3 Rotate the converter to align the low-magnification objective with the clear aperture (the front end of the objective lens and the stage should be kept at 2 centimeters.)

meters).

4 Align a larger aperture at the aperture. The left eye is fixed inside the eyepiece (the right eye is open so that the picture can be drawn at the same time later). Turn the mirror so that the light is reflected into the barrel through the aperture. Through the eyepiece, you can see a white and bright field of vision.

3. Observation 5 Place the slide specimen to be observed on the stage.

6 Turn the coarse collimator spiral so that the lens barrel is slowly lowered until the objective lens is close to the slide specimen (eyes look at the objective lens so that the objective lens does not touch the slide specimen).

7 The left eye looks into the eyepiece and at the same time turns the coarse collimation spiral in the opposite direction so that the lens barrel slowly rises until the image is clearly visible. Then turn the fine collimation spiral slightly to make the image of the object seen more clearly.

Isn't it six?

I'll look at science books! Wood has eh.

You can go to Zhejiang Education Press** to find it, or Renming Education Press** to find it.

Good luck..

1. Take the lens. 2. Placement.

3. To the light. 4. Observation.

5. Summary.

How to use the microscope:

1 Hold the arm with your right hand and hold the base with your left hand.

2. Place the microscope about 7 cm away from the edge of the laboratory table, slightly to the left. Attach the eyepiece and objective.

3. Rotate the converter to align the low-magnification objective with the clear hole.

4 Align a larger aperture at the aperture. The left eye is fixed inside the eyepiece. Turn the mirror so that the light is reflected into the barrel through the aperture. Through the eyepiece, you can see a white and bright field of vision.

5. 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.

6. Rotate the coarse collimation spiral to slowly lower the lens barrel until the objective lens is close to the slide specimen Zao Luhu.

7. Look into the eyepiece with the left eyepiece, and at the same time rotate the coarse quasi-focal spiral in the opposite direction, so that the lens barrel will rise slowly until the image is clearly seen. Then turn the fine collimation spiral slightly to make the image of the object seen more clearly.

Precautions: After the experiment, wipe the surface of the microscope clean. Turn the converter to deflect both objectives to the side of the stool and slowly lower the barrel to the lowest point. Finally, put the microscope in the case and return it to its original place.

1. Turn the low magnification lens to the bottom of the lens barrel in a straight line with the lens barrel.

2. Toggle the reflector and adjust it to the brightest field of view without shadows. The reflector has two sides, flat and concave, when the light source is strong, use a flat surface, use a concave surface when it is dark, and when you need strong light, raise the condenser and enlarge the apertureWhen low light is required, lower the condenser or shrink the aperture appropriately.

3. Place the specimen to be observed on the stage, and turn the coarse adjuster to lower the lens barrel to the point where the objective lens is close to the specimen. While turning the coarse regulator, you must lean over the mirror and carefully observe the distance between the objective lens and the specimen.

4. The left eye is observed in the eyepiece, and the left hand is rotated to adjust the lens barrel slowly to adjust the focal length, so that the objects in the field of vision will stop when they are seen until the specimen is clear.
