Commonly used microscopes are binocular continuous zoom stereomicroscope, metallurgical microscope, polarizing microscope, ultraviolet fluorescence microscope and so on.
1, binocular stereomicroscope in the biological and medical fields are widely used in sectioning operations and microsurgery; in industry for tiny parts and integrated circuits for observation, assembly, inspection and other work.
2, metallurgical microscope is specially used to observe metals and minerals and other opaque objects metallurgical organization of the microscope.
3, television microscope and charge-coupled device microscope is a television camera target or charge-coupled device as the receiving element of the microscope.
4, scanning microscope is the imaging beam can be relative to the object surface of the scanning motion of the microscope .

Precautions:
1, experiments should be the microscope Put the microscope on the table slightly to the left of the position, the mirror base should be about 6-7 cm from the edge of the table.
2. Turn on the light switch and adjust the light intensity to the appropriate size.
3. Turn the objective converter so that the low-magnification lens is facing the light hole on the carrier table. First, adjust the lens to about 1 to 2cm from the carrier stage, and then use the left eye to look into the eyepiece, and then adjust the height of the condenser, the aperture diaphragm adjusted to the maximum, so that the light through the condenser into the lens barrel, which is bright in the field of view.
4, the slide to be observed on the carrier table, so that the part of the slide to be observed is located in the center of the aperture, and then use the specimen clip to clip the slide.
5. Observe with low magnification first (objective 10X, eyepiece 10x). Before observing, turn the coarse focusing handwheel to make the stage rise and the objective lens gradually approach the slide. Care needs to be taken so that the objective lens does not touch the slide to prevent the lens from crushing the slide.
Then, the left eye looking into the eyepiece, at the same time, the right eye is not closed (to develop the habit of observing with both eyes open with the microscope, so that while observing with the right eye looking at the drawing), and rotate the coarse focusing handwheel, so that the stage is slowly lowered, and will soon be able to see the magnification of the material in the slide object image.
6, if the image seen in the field of view does not meet the requirements of the experiment (the image deviates from the field of view), you can slowly adjust the moving handle of the carrier stage. Adjustment should be noted that the direction of the slide and the field of view to see the image of the direction of movement, just the opposite. If the object image is not very clear, you can adjust the micro-focusing handwheel until the object image is clear.
7, generally have the normal function of the microscope, low-power objective lens and high power objective lens is basically in focus, in the low-power objective lens observation is clear, change the high power objective lens should be able to see the object image, but the object image is not necessarily very clear, you can rotate the micro focusing handwheel to adjust.
8, in the conversion of high-magnification objective and see the object image, according to the need to adjust the size of the aperture diaphragm or the height of the condenser, so that the light meets the requirements (generally will be low-magnification objective into a high-magnification observation, the field of view to be a little darker, so you need to adjust the light intensity).
9, observation is complete, the objective lens should be removed from the light hole, and then the aperture diaphragm adjusted to the maximum, and then the carrier table slowly fall, and check the parts have no damage (pay special attention to check whether the objective lens is stained with water stained with oil, such as stained with water or oil to be wiped with a lens paper), check the processing is complete can be boxed.
