Concept in Definition ABC

The magnifying glass is a tool optic made up of a lens convergent and with a suitable frame adapted to the purpose for which it will be used.
The converging lens is short distance focal point and produces a deflection of light incident in such a way that it forms a picture virtual enlarged object or written behind it. This resulting image is called virtual because the rays that seem to come from it do not actually pass through the magnifying glass.

The main mission of the magnifying glass is to offer the person who manipulates it the magnified view of an object, document, written, among other issues.

The maximum angular size that humans achieve simply by observing with our eyes can be obtained by bringing the object closer to the eye, but of course, the latter is incapable of being able to focus at distances very, very close to the next point, meanwhile, the magnifying glass, superimposed on the eye, achieves it, allowing the eye to approach the object in question.

There are different types of magnifying glasses, with different curvatures, for example, while the larger magnifying glasses diameter They turn out to be the most powerful since they allow a greater curvature of the surfaces, as a consequence of being the narrowest glass in the periphery and thick in the center.

Most of the magnifying glasses are mounted on a circular type support that also has a handle that facilitates its driving and grip. Anyway, they are manufactured in super specific formats for the different applications it may have, such as: reading, watchmaking, philately, among other.
