Overview 5 kinds of microscopes for the best schoolboy: how to choose which one to buy, the pros and cons, features, rating

Microscope - one of the most important instruments for research in different laboratories, research centers, and even in the workplace. He is actively used by radio amateurs in the home for fine detail work, and on the lessons of biology under the microscope teacher opens the wonderful world of children living cells and organisms, which can not see with the naked eye. By purchasing this device student, you can give him the opportunity to engage in independent study most interesting microcosm, from an early age to instill love and respect for science.

How to choose a microscope schoolboy

Ordinary buyer is difficult to understand in a variety of microscopes on the market today for optical instruments. Given that the different models have their own design and specifications, it is important to choose suitable for a student model, not overpaying, but are not limited to the child's desire to learn new substandard instrument. When you purchase should focus on the following selection criteria.

increase

The simplest models have a magnification of 200 times, but the interest of the child can quickly evaporate if we will see little detail. For high school students better to pick up a microscope at 400-fold or more, and if the child is in the future plans to become a biologist or a laboratory, it is necessary to increase the unit more than 1,000 times.

backlight

At the microscope illumination can not be at all, but it happens in a normal machine:

• The bottom - it's either a separate lightbulbLocated under the stage, illuminates study medication through an aperture or a mirror that reflects external light.
• Top - the stage is illuminated by light falling from above. Suitable for the study of non-transparent objects, such as beetles.

Better to choose the model, which combined both types of illumination, it is desirable that the light source were aimed LEDs. Such a microscope is more versatile.

Eyepiece

Optical monocular microscope, that is, one which looks with one eye, much cheaper binocular models. It has a compact size, allows the eyepieces with other characteristics of multiplicity. Their increase can reach 1500 times. They are easier to handle, because for a student - is the best option. To display an image on a computer monitor equipped with modern appliances videookulyarom.

Digital microscopes do not allow to look at the object through the optical eyepiece due to his absence, but the output image of the test object on the built-in small screen. These options are more expensive, have a built-in memory, are able to take photos and even record video. Advanced models can also display images on the projector televisions.

Lenses

To explore the microcosm fit microscopes with one lens, the magnification is chosen by replacing the eyepiece. More advanced models, the cost of which is also higher, at the same time have 3-4 lens mounted on a revolving mechanism.

accessories

Buying a microscope for the student, it is important to make sure that in its present complete accessories, without which the full investigation of the microcosm will be almost impossible:

• Slides - thin slices of plants that are placed on a slide and are pressed against the cover. Slides are made under sterile conditions, and on the basis of their own child can create a unique product for the experiments. A set of such drugs can be purchased separately, if all of a sudden was not complete.
• Set for experiments - all sorts of tubes, pipettes, forceps, incubator for shrimp (microscopic crustacean).
• Microtome - toolWhich allows the sections of biological tissue to 0.5 mm thick. It can also be purchased separately.

In addition to the above, in the box should include an additional coating and slides. It is worth to the presence of Keyes or hard shell case for transportation.
