If only multiples are pursued, then this multiplier is true. 10000 times The general highest magnification configuration is 100x objective lens + 2x extender lens + 50x eyepiece, at this time the multiple is 100x2x50 = 10000 times, and professional users such as hospital testing will only choose 1000 or 1600x microscopes.
As a merchant who has been engaged in the microscope industry for many years, I will tell you that the optical microscope should not pursue the multiple, the multiple is not the core parameter of the microscope, and the quality of a microscope is its resolution. The resolution is directly proportional to the NA value of the objective, and the higher the NA value, the higher the resolution.
Closely related to the NA value is the effective magnification of the microscope: between 500NA-1000NA, the NA value of an ordinary optical microscope is the largest, then its effective magnification is the maximum 1250 times, with 10 times or 16 times eyepieces, the total magnification does not exceed 1600 times, and a little larger is 2000 times.

Light microscopy.
10,000 times is fake.
The maximum objective lens of the optical microscope is 100, and the objective lens at this time should use cedar oil, that is, oil lens.
Eyepieces are generally used with 10
There are no 100 eyepieces.
The magnification is less than 10,000x.

Yes, what you said is very correct, the multiple of the optical microscope is true, but because it is used less, many people are reluctant to leave here, so we think that the optical microscope is true in all this case, and the 1000 mouth has not changed at all.
-
Isn't 10,000 times only an electron microscope? It is impossible for an optical microscope to be 10,000 times greater. Optical microscope objective lens 100 is to use pine cedar oil, that is, oil lens, eyepiece can not reach 100, so the overall magnification of 10,000 times is impossible!
It's all a lie! It's not reliable at all! Be careful!

Bacteria etc. can be seen.
The structure of an ordinary optical microscope is mainly divided into three parts: the mechanical part, the illumination part, and the optical part.
1.Mechanical part.
1) Lens holder: It is the base of the microscope to support the entire mirror body.
2) Mirror column: It is the upright part of the mirror base, which is used to connect the mirror base and the mirror arm.
3) Mirror arm: One end is connected to the mirror column and the other end is connected to the lens barrel, which is the part of the hand when taking and placing the microscope.
4) Lens tube: Connected to the front of the mirror arm, the upper end of the lens barrel is equipped with an eyepiece, and the lower end is equipped with an objective lens converter.
5) Objective lens converter (rotator): connected to the bottom of the prism shell, can rotate freely, there are 3 4 round holes on the disk, which is the installation of the objective lens part, rotate the converter, you can change the objective lens of different multiples, when you hear the knocking sound, you can observe, at this time the optical axis of the objective lens is just aligned with the center of the light hole, and the optical path is connected.
6) mirror stage (stage): below the lens tube, the shape is square and round, used to place the slide specimen, there is a light hole, the microscope we use is equipped with a slide specimen propeller (push table) on the mirror table, there is a spring clamp on the left side of the propeller to clamp the slide specimen, and there is a propeller adjustment wheel under the lens table, which can make the slide specimen move left and right, front and back.
7) Adjuster: It is two kinds of spirals installed on the mirror column, which makes the mirror table move in the up and down direction when adjusting.
Coarse Adjuster (Coarse Spiral): The large helix is called the coarse adjuster, which can make the lens table rise and fall quickly and with a large radiance when moving, so it can quickly adjust the distance between the objective lens and the specimen to make the object image appear in the field of view.
I hope I can help you with your doubts.

The general objective magnifications of a microscope are as follows:
4 times, 10 times, 40 times, 100 times, the regular configuration of the eyepiece is 10 times, and there are also 16 times the ruler hunger, 20 times, etc. If required, the total magnification can be obtained by multiplying the magnifications of the eyepiece and objective lens respectively.
Maintenance of the microscope:
1. If the room is humid, the optical lens of the limb is easy to mold and fog. Once the lens has mold, it is difficult to remove it. The lenses inside the microscope are inconvenient to wipe, and moisture is more harmful to them.
2. After the mechanical parts are damp, they are easy to rust. In order to prevent moisture, when storing the microscope, in addition to choosing a dry room, the storage place should also be away from the wall, the ground, and away from the moisture source. 1 2 sachets of silica gel should be placed in the microscope box as desiccant.
and often bake the silicone. After its color turns pink, it should be baked in time and continued to be used after baking.
3. Dust falls on the surface of the dust-proof optical Yuanchun trapped world, which not only affects the passage of light, but also generates large stains after being amplified by the optical system, which affects the observation. Dust and sand particles falling into the mechanical part will also increase wear and tear, causing movement obstruction, and the harm is also great. Therefore, it is essential to keep the microscope clean frequently.

A 1200x microscope can see microorganisms.
1200 times the light microscope 1200 times can see microorganisms, elementary school to high school students are most suitable for adjusting the microscope to 1000 times, 1000 times is the clearest to see, after 1000 is a little blurry, so 1200 times the light microscope can see microorganisms.
Microbial Science:
Microorganisms are all tiny organisms that are difficult to see with the naked eye and can only be observed with the help of an optical microscope or electron microscope. A large group of organisms, including bacteria, viruses, fungi and some small protists, microscopic algae, etc., which are small and closely related to human hosiery. It covers many kinds of beneficial and harmful, and is widely involved in food, medicine, industry and agriculture, environmental protection, sports and many other fields.
In textbooks in Chinese mainland and Taiwan, microorganisms are divided into the following 8 categories: bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia, and spirochetes. Some microorganisms can be seen with the naked eye, such as mushrooms, ganoderma lucidum, shiitake mushrooms, etc., which belong to fungi.
There are also microorganisms that are non-cellular organisms that are composed of a few components such as nucleic acids and proteins, but their survival must depend on living cells.
A general term for all microscopic organisms that are difficult for an individual to observe with the naked eye, including bacteria, viruses, fungi and a few algae. (However, some microorganisms are visible to the naked eye, such as mushrooms, reishi, etc., which belong to fungi.) )
Viruses are a class of non-cellular organisms made up of a few components such as nucleic acids and proteins, but their survival must depend on living cells. According to the different environments present, it is divided into space microorganisms, marine microorganisms, etc., and according to the classification of cell structure, it is divided into prokaryotic microorganisms and eukaryotic microorganisms. <>

A 1200x microscope can see microorganisms.
If you adjust the microscope to 400 times, you can barely see bacteria, and under the microscope of 400 times, the microorganisms you can see are only the size of a needle tip, so 1000 times can see microorganisms, if you adjust the optical microscope to 1200 times, you can see bacteria, but it is half more blurry than the original.
Notes on Microscopy:
1. It is necessary to abide by the rules and regulations of the middle branch of the operation, and operate strictly and conscientiously according to the requirements. When picking up and delivering the microscope, hold the lens arm with your right hand and hold the lens holder with your left hand. Do not use one hand to lift diagonally, swing back and forth to prevent the eyepiece from slipping out and falling.
2. Protect the lens, wipe the dust or dirt on the eyepiece and objective lens, and use the lens wiping paper. Never wipe with fingers, handkerchiefs, pewi gauze, and plain paper.
3. During the microscopic examination, sit upright, generally observe the object with the left eye, and look at the experimental report paper with the right eye to draw the picture. Keep both eyes open at the same time to reduce fatigue. <>
