It also enlarges the working space by illuminating the object and the area around it. The optical power of such devices is usually 2-4 diopters. The combination of magnification and lighting helps to more competently solve many of the tasks. Such opportunities are especially required in cosmetology, medicine and biology.
The magnifying glass has an additional functional detail - an ultraviolet light used to check banknotes . This feature is very convenient for merchants and cashiers to see watermarks under UV light and other small details under a magnifying glass.
Views
Clamp loupes are of different types. Loupes come in different shapes depending on the purpose of their application.
- Round tabletop … It is used in good lighting conditions when no additional light source is required.
- Square . Basically, these are ruler magnifiers for measuring and reading books.
Magnifiers on a tripod also differ in the type of lighting
- LED … It is used to illuminate the work surface. This type of clamp magnifier has LED illumination built into the body.
- Ring lamp . This model has very powerful object illumination. Most often, devices with lamp light are used in cosmetology and medicine.
Model overview

The light emanating from the lamp is even, without flicker, which makes it possible to use this device in working conditions in low light. The magnifier is mounted on a gooseneck. With its help, it is convenient to move the optical glass over the surface and set the direction of the light. The lens is made of high quality optical material and has a 5x magnification. Indispensable for soldering small objects in radio engineering.
The advantages of these models include:
- economical energy consumption;
- fairly high magnification, suitable for working with small details;
- the presence of a flexible tripod, mobility at work;
- uniform illumination makes it possible to use the device in complete darkness;
- lens made of high quality optical material.
As a minus can be highlighted rather big weight of the device , which makes it non-compact and therefore not a pocket-sized product. These devices are classified as stationary equipment.
How to choose?
To determine the choice of one or another option, you should decide what the device will be used for: for professional or domestic use. All magnifiers differ in the area of operation.

- The main selection criterion is the magnifying ability . First of all, the magnifier is designed to enlarge the image of small objects. When selecting, you need to pay attention to the multiplicity of the device. It is measured in diopters and is directly related to focal length. The more diopters, the higher the magnification.
- Design feature . Depending on the purpose of use, magnifiers have a different structure. In addition to cosmetology and medicine, clamp magnifiers are widely used in agriculture.
- Material , from which the lens is made: optical polymer, glass, acrylic plastic. Lenses made of glass and optical polymer have the highest optical and technological parameters. Glass optics are much heavier than devices made from polymer. The lightest and cheapest plastic lenses, but they are inferior in quality and wear resistance. Polymer and glass optical lenses are not subject to light to medium mechanical stress. They are stronger and more durable.
- And also you should pay attention to manufacturer and prices … The most popular brand of clamp-on loupes is Rexant. This manufacturer specializes mainly in this type of device, complementing them over time with various innovations.
Application

Enlarging the image of small objects and parts of mechanisms … The main characteristic of magnifying glasses is magnification. The higher it is, the better you can see objects in the distance, and the wider the field of view you can cover. An optical device with 5 diopters magnifies the image by 2, 25 times. And with a multiplicity of 20 - 6 times. People with visual impairments, myopia, may need a magnifying glass with a magnification of 5, 10 and even 20. A person with a slight decrease in vision to read books needs a device with an optical power of 3 diopters, which magnifies the text by 1.75 times.
Measurement of objects . There are special magnifying glasses equipped with a ruler. A scale is applied to the entire length of the lens. The measurement step can be different: 1–5 mm. It is selected depending on the upcoming measurements.
With the help of these devices, you can not only examine the subject in detail, but also measure it.
Illumination of the viewing area … Some optical devices are equipped with LEDs and can not only enlarge the image of an object, but also illuminate it.
