1, take the mirror and place ① Hold the mirror arm with the right hand and the mirror base with the left hand. ② Place the microscope on the experimental platform, slightly to the left. Install eyepiece and objective lens.

2. Align the light ① Turn the converter so that the low-power objective lens is aligned with the light hole ② and the larger aperture is aligned with the light hole. Leave the left eye in the eyepiece and open the right eye for later observation and drawing. You can see a bright field of vision by turning the mirror.

3. Observation ① Place the glass slide to be observed on the stage, press it with a tabletting clamp, and the specimen should face the light hole. (2) Turn the coarse focusing screw to slowly lower the lens barrel until the objective lens is close to the slide, and keep your eyes on the objective lens to prevent it from touching the slide specimen.

③ Look at the eyepiece with the left eye, and at the same time, rotate the coarse focusing screw reversely, so that the lens barrel rises slowly until the object can be seen clearly. Then turn the fine focusing screw slightly to make the image of the object clearer.

Application of microscope

1. In scientific research, microscope is an important tool in cytology, genetics, microbiology and biochemistry. Through the microscope, scientists can observe and study the structure of cells, the morphology of microorganisms, the replication process of genetic material and so on.

By observing the morphology and behavior of bacteria under the microscope, we can study their biological characteristics and formulate corresponding treatment methods. Microscope plays an irreplaceable role in life science research.

2. In the medical field, microscope is widely used in clinical diagnosis and pathological research. Doctors can use microscopes to observe cells, tissues and organs in patients to help diagnose diseases and determine treatment plans.

In pathological research, microscope is used to observe tissue sections and cell specimens to determine the type and degree of diseases. The application of microscope in medicine plays a key role in the early diagnosis and treatment of diseases.

3. Microscope has many applications in material science. The research of materials science involves the study of the structure, properties and properties of materials. The crystal structure, micro-morphology, defects and impurities of the material can be observed by microscope. This information can help researchers better understand the characteristics of materials and develop new materials with better performance.

Microscope also has important application in the field of education. Widely used in teaching laboratories, students can understand the micro-world of nature through observation and experiment, and cultivate their observation and experimental skills. Through the microscope, students can observe many tiny structures and microorganisms that they can't see at ordinary times, thus deepening their understanding and interest in scientific knowledge.
