Hello and welcome back. This time we will be looking at a piece of equipment that is useful for glimpsing things with a small size or for repairing objects that require a lot of precision. We are referring to the loupes with light, an optical instrument to magnify small objects with ease.

Magnifying glasses with light are instruments that consist of a convex lens that helps the eye to converge by the refraction of the light of the object that is placed under it. These magnifiers incorporate an illumination system in their lower frame, which allows us to work with these magnifiers even in low light conditions.

We want to help you find the best magnifier with light that suits your needs and the work you are going to do with this equipment. That's why we'll show you the various shapes and sizes that lighted magnifiers can come in, along with the main features and benefits they provide.




Summary

  • Lighted magnifiers are instruments for magnifying objects underneath the magnifier in order to be able to see their parts in detail. They have an illumination system whose purpose is to better illuminate the object to be examined and to be able to work in conditions where different light sources are scarce.
  • In the world of magnifying glasses we can find a wide variety of models of these magnifying instruments. Although they all have the same function, we can classify them into two groups: lighted magnifiers and normal magnifiers that do not have an illumination system. Each offers advantages according to the work to be done.
  • Knowing about the dioptre to choose, the focal length and the field of vision will help us when we are going to acquire a good loupe with light for our activities. Knowing each of these factors will make our purchase more comfortable and effective when choosing between the different lighted magnifiers on the market.

The Best Magnifier With Light: Our Picks

Buying guide: What you need to know about lighted magnifiers

Thanks to lighted magnifying glasses, we can check objects and things that we would not be able to see easily with glasses or the naked eye. In this section you will learn about the advantages of lighted magnifiers, the different models available and the costs they have on the market.

What is a lighted magnifier and what are its advantages?

Lighted magnifiers are precision instruments that magnify very small objects or components so that they can be viewed at a comfortable size. To make this possible, lighted magnifiers have a converging lens with a short focal length that allows the light falling on it to be deflected to magnify the size.

In addition to the converging lens, loupes with light incorporate an illumination system around the lower edge that holds the lens, which provides the possibility to improve the quality of light in order to see the object under the loupe in better detail. Also, it allows better work in places with a poor light system.

There are many uses for loupes with light. From the medical field to the aesthetics and electronics fields, to name but a few, they are used to access areas that are difficult to see with the naked eye.

Advantages
  • They come in various shapes and sizes
  • They magnify small objects
  • They are economical
  • They allow working in low light conditions
  • They are easy to handle
Disadvantages
  • They are very delicate objects
  • Certain models have a limited working range
  • They require maintenance of both the lens and the illumination system

Lighted and unlit magnifiers - what should you pay attention to?

In the market of optics and lenses, we can find a large number of instruments to see better. Among this equipment are magnifying glasses and in the case of these working tools, we can place them in two models: lighted magnifying glasses and unlighted magnifying glasses.

Magnifying glasses with light. This model has a convex lens that magnifies the size of the object being observed. It also has a light system in its lower part to give a better sharpness and quality of luminosity to the product that is looked at with it. This system can be battery operated or mains powered.

Magnifiers without light. They use the same principle as lighted magnifiers. They have a convex lens to magnify the image, but lack an illumination system. This limits them when working with them, as they will be difficult to use in dimly lit spaces to observe the detail of small objects

Magnifier with light Magnifier without light
Uses Medicine, Electronics, Jewellery, Aesthetics and Reading Reading, research and crafts
Shape Table, Wall and Portable Portable and Tabletop
Advantage They allow you to work even in dimly lit spaces No need to connect them to a power socket or change batteries

What about portable, table and wall magnifiers with light?

Within the world of illuminated magnifiers, there are various presentations of these vision tools. They can be grouped into three models: portable loupes with light, table or desk loupes with light and wall-mounted loupes with light.

Portable loupes with light. This is the classic model par excellence. They are portable because they are small and easy to carry. Their lens is held by a frame which has a handle so that it can be held by hand. They are the most mobile magnifiers.

Table magnifiers with light. Designed to be placed on tables or desks, table magnifiers have a base and a flexible arm that can be moved to a certain point. Some models of table magnifiers have a clamp system to hold the object to be inspected and keep your hands free.

Wall-mounted magnifiers. These magnifiers partly copy the design of the table model, except that they do not have a base. In this case, wall-mounted magnifiers can have a plate at the bottom to be screwed to the wall or a system of hinges to be placed in corners.

Purchasing criteria

The use of lighted magnifiers is ideal and essential when you are doing work that requires precision on very small objects. But before you go out and buy your lighted magnifier, you should be aware of certain factors that will make your purchase safer.

We will elaborate on each of these points in more depth so that you have a more precise and concise understanding of what to look for when you want to buy a lighted magnifier for your daily activities.

The Diopter to Choose

This element refers to the curvature that our lighted magnifier has. Increasing the dioptre makes the lens much thicker and has a greater curvature; and the opposite happens with decreasing the dioptre.

If the curvature is increased, the light rays are redirected to fill a larger portion of our retina so that the object under the magnifying glass can be seen larger. This is why we must pay attention to the dioptre. If the dioptre is higher, the magnification of the lens will increase, but if it is lower, the magnification will decrease.

The Focal Distance

This is one of the factors to consider when purchasing a loupe with light. The focal length is understood as the distance from the centre of the lens to the point where the light rays converge on the object to be magnified to achieve optimum focus; this is known as the focal point or the working distance of the lens.

The focal length turns out to be very important, especially when working with instruments on the magnified object. This is because the higher the power increase, the shorter the focal length; this means that we have less field of view to work with the higher power lenses.

Depending on the work to be carried out with the loupe with light and if we are going to incorporate other elements below it, we must select an equipment whose focal length allows us to work comfortably without losing detail of all the components that are within the work area.

The size of the field of view

In the use of loupes with light, the field of view is the size of the magnified area under the lens that is in focus. As the field of view decreases, the power of the lens becomes greater. Lenses that are more powerful make small details appear large, but less of the total object is seen.

That is why when we want to buy a lighted magnifier we must choose between the field of view we want and the amount of magnification we can achieve with our lens, as these two elements correlate with each other.
