What is a magnifying glass and what increase does it give?

Almost everyone at home has at least an ordinary household magnifier with a small magnification. Perhaps this simple optical device is rarely used, but sometimes it becomes an extremely necessary thing.

However, few people seriously think about the magnification of the lens. In other words, how much the magnifying glass magnifies objects is often unknown to the owner, although knowledge of this characteristic makes it possible to use the device more efficiently.

In various fields, you cannot do without such a useful device as a magnifying glass. Used correctly, it can simplify many of the tasks people face. You should take a closer look at this subject and learn how to choose it correctly.

As already mentioned, the magnification factor directly depends on the focal length. The latter is determined by the curvature of the product. The larger it is, the less focus. The smaller the focus, the higher the magnification. The smaller the diameter of a commercially available lens, the greater the values ​​of its curvature and, of course, magnification. Thus, if the curvature is less, then the diameter of the product will be larger, and the multiplicity will be less. Simply put, a wide loupe allows you to see a large area, but with a small increase. The small diameter magnifier magnifies well, but covers limited space.

Small magnifiers usually distort the objects in question. When choosing a simple household magnifying glass, you will have to make a choice either in favor of the covered space or in favor of quality. Products with a double lens are considered the best option. In the case of the subsequent purchase of an expensive product with several lenses, the problem of choosing between image quality and coverage is eliminated. Such settings can provide both high definition images and wide coverage. But they are distinguished by their large dimensions and impressive weight.
