Deciphering small fonts is permanently exhausting for the eyes. Fortunately, all details can be magnified by a magnifying glass. But how does it work? Where is she used? And how is it structured? Learn more about the operation of a magnifying glass and its uses in the following article.
How does a magnifying glass work?
To understand the magnifying glass function, one has to understand the process of seeing. When the light illuminates an object, the object reflects that light in the form of rays. These get into the eye and are processed into a picture. For the assignment of the size of the observed object, the eye uses two light beams, on the one hand, the ray of light emanating from the top of the object and, on the other, the ray of light radiated through the lowest point. These rays of light fall into the eye at a specific angle. Imagine a candle. The first ray of light emanates from the topmost tip of the flame, the second from the lowest edge of the wax. Together, the light rays from an angle, imaginable as a triangle. This determines how much you perceive the object.
A magnifying glass enlarges the angle through a lens. A lens is a component with a curvature. Loupes work with convex (convex) convex lenses. Such a lens breaks the light rays and changes the angle. The rays are now at an enlarged angle to each other and create a so-called virtual image. This refers to the magnified image of the object.
How is a magnifying glass constructed?
A magnifying glass has two parts: a holder and a convex condenser lens. The holder covers the lens and allows safe handling. The working lens of the magnifying glass is the condenser lens. It consists of glass and enlarges the object under consideration.
Who uses magnifying glasses?
Reading magnifying glasses and other magnifying glasses help to recognize details of an object and are used in different areas.
In everyday life, we encounter small writings, such as in the packaging supplement of a drug. A reading magnifying glass or a magnifying lamp can help and make the reading process easier. If you can not easily see what is happening on your computer screen, we recommend using the magnifier. You can activate the magnifier in the settings.
In the medicine
In the medical context, magnifying lamps are an aid. With a magnifying glass, dermatologists examine birthmarks for irregularities.
Loupes are involved in the investigation of crime. The enlarged image makes it easier to inspect tracks. This includes, among other things, the observation of insects, which provide information about the time of the death of a person.
In other professions
In many professions, precise work is required. That’s why watchmakers, goldsmiths, jewelers and precision mechanics use magnifying glasses.
Conclusion: Loupes as manipulators of the light rays
Loupes are useful tools that work on a simple principle. To be able to perceive objects, people are dependent on light rays. The angle of the rays of light gives information about the size of the object. Loupes change the angle and make the picture appear larger in this way. Thus they facilitate the reading, but also the work in medicine, criminalistics and other areas.
