Working with a digital microscope

 

The use and application of a digital microscope in various industries is widely used due to the ability to see small objects with the naked eye under their optical magnification. Thanks to digital equipment and equipment, this can be done not through the eyepiece, but directly on the monitor screen or on any other medium with a display. Working with a digital microscope brings only pleasure for the researcher, since the result obtained is taken directly to a digital camera or immediately displayed on a computer. These microscopes are very expensive and therefore not available to everyone. But publishers have embraced a more social proposal, with the microscope incorporating a photosensor embedded directly into the microscope's eyepiece, thus representing a modification of the best usb microscopes.

 

Digital microscope : the software enables the person who conducts research or observation to view objects and objects directly on the monitor, even the smallest. Such microscopes are especially popular not only among medical and scientific workers, but are also an integral part of the work of jewelers, coiners, workers with microcircuits, and so on.

The characteristics of a digital microscope directly affect its price. When choosing a microscope, it is very important to pay attention to the optics, the resolution of the microscope, as well as the matrix that is used in it. The multiplicity of magnification, its software, as well as the quality of the materials used are of no small importance for obtaining the research result.

Digital microscope overview

Before proceeding with the review of the microscope, I would like to say right away that it can be desktop and portable, which will be their main difference. So, a desktop digital microscope consists of a stage on which several light sources are located (lower and upper side). The head section of the microscope contains three objectives of different magnification, a sensor for the resulting image and a panel on which connectors are located for obtaining an image in a digital form.

 

 

 

How to use a digital benchtop microscope? We often get these kinds of questions, so let's briefly dwell on it. So, the subject of research is placed on the slide, which is placed on the slide under the light source. Having fixed the slide, it is required to adjust the lighting: if it is a transparent object (research material), then use the lower lighting, and if it is opaque, then the upper side lighting. In rare cases, you have to resort to using both light sources. The study starts with a low frequency lens and then uses more powerful lenses.

 

A portable digital microscope is a device that contains a built-in matrix located inside a plastic tube. Unlike a desktop digital microscope, such a microscope has only manual focus adjustment and the simplest illumination using LED lamps. The resulting image using the USB system is immediately transferred to a computer or another matrix, previously connected to it.

 

A digital microscope - we briefly told you about its description, but now we will talk about how to use it. Many people find it difficult to work with a digital microscope. But we want to assure you that it is not only simple, but also convenient, because the resulting image is immediately displayed on the monitor screen and allows you to see the object under study in more detail, with high resolution by several specialists at once. Before you start working with your digital microscope, you need to install the software on your computer, the disk with which comes with it. After downloading the program, the computer has to restart, turn on the microscope and use a cable to connect it to the computer. In fact, there is nothing difficult, so before you buy a microscope - think about it, set a specific goal before buying it.

Weight / power ratio: do the math before buying the next car

 

Have you ever heard of power weight? There is a simple account to do whose result will help you a lot when buying a car. To obtain the value of the Weight / Power ratio, simply consult the vehicle's technical sheet on automotive websites, car magazines and even more complete price tables such as that of Jornal do Carro (SP). View here for more info: average car weight

Take the weight of the vehicle in kilograms (Kg) and divide it by the horsepower of the engine in horsepower (cv). So, in the case of a Chevrolet Onix 1.0, you will have:

1011 Kg / 80 hp = 12.63  Kilo per hp

This means that each horsepower of the Onix in question will carry a little more than 12 kilos. In my view this result is important because it indicates that the car is economical, but it is not so fast and that due to the weight it should not come with many safety equipment and will have a popular car price.

However, I agree that at first glance, without comparison parameters it seems to be just a number. How do you know if a power to weight ratio of 12 is too little or too much? I'll clarify more. I will not make a racing list or a ranking of power-to-weight ratios of all the cars on the market here . I will comment on the results by category (popular, compact, medium sedans, small pickups, SUVs etc.) giving examples of some models , so that you have an idea of ​​how your car performs and the positive and negative highlights of the category, if any.

It is worth remembering that the maximum power is always obtained with Ethanol when the car is flex and that the weight is that of the version of that car that has that type of engine, 1.0 or 1.6, for example.

Best option - Renault Kwid

 

  

As the 1.0 cars have little power, the small differences between the models make a big difference in practical day-to-day use. Note that Fiat models, with a maximum power of 77 horsepower, have very poor power / weight ratios, with the exception of Mobi. Uno and Argo have the worst numbers, along with the Nissan Versa. The highlights are Renault Kwid, Volkswagen Gol and Volkswagen Up. The Kwid is ahead because it is much lighter than the others, and VW models stand out because they have 82 horses, more than almost all, second only to the Ford Ka , which did not win because it is very heavy.

Best option - Hyundai HB20 1.6 and Nissan March 1.6

Here things have improved a lot, we find weight / power ratios much more interesting. We have the exceptions, heavy and low power models, such as VW Fox 1.6, Peugeot 208 1.2 and Citroen C3 1.2, these last two models made to deliver economy and not power. At the other end, the Hyundai HB20 1.6 has an excellent power-to-weight ratio, which comes close to the values ​​of sports compacts, with a great 8.12 kilos per horse. The Nissan March is also great at that.

Best option - Hyundai HB20S 1.6

Here, all compact sedans with engines between 1.3 and 1.6 are very close together, with the exception of the Hyundai HB20S 1.6, which stands out positively. And the other highlight is negative, the Grand Siena 1.4 cannot reach its opponents and is well behind, with more than 12 kilos per horse.
