The magnifying glass is a versatile device that can be used to perform a wide variety of work with very small parts. The magnifier is used to repair phones, smartphones, computer equipment, and is used to solder boards in radio and electronic products.

Many critical components and parts that need to be repaired require precision and accuracy, such as in a watch movement, and here a magnifying glass comes to the rescue of the master, which greatly facilitates the work and allows you to achieve excellent results. In this case, magnifiers with illumination are considered more convenient, since most of the operations performed by the master require jewelry accuracy and a good view.

It is impossible to perform high-quality diagnostics if the inspection of parts is difficult due to their small size and poor illumination. In addition to diagnostics, a magnifying glass is also used to monitor the result of work performance. For example, the high quality of soldering or assembly guarantees trouble-free operation of the mechanism, which means that the repair was not done in vain.

If a person has reduced visual acuity, without a magnifying glass it will be difficult for him to read, write, embroider or perform other everyday activities that require clarity and a good view. The magnifier can be built-in illumination - LED or fluorescent lamps, and the size of the magnifying glass itself can be small or quite extensive. The magnifier can be bracket-mounted, floor-mounted or table-mounted. Most often, the design of a magnifier allows you to work with two hands without being distracted by its support.

Advantages and disadvantages

The purpose of a magnifying glass is to visually enlarge the image. Through it, you can see small details that are not visible without visual magnification. Watchmakers and jewelers usually use forehead magnifiers for convenience. Head-mounted loops have many advantages.

• Freedom of hands. When attaching the magnifier to the forehead, the hands are free and can perform various actions, which is necessary for the repair of any mechanisms.
• Durability. This type of optics is made of wear-resistant materials. The product is not afraid of mechanical damage.
• Light weight of the device. Does not cause discomfort when used.
• Small size.
• Ease of use. Holds securely, there is an eye mount.

If the product is illuminated, it provides:

• a good detailed overview, you can see the smallest elements;
• allows you to work in low light conditions.

The disadvantages of such optics may be low functionality and inconsistency with modern requirements, if the product is of a dubious brand and very low cost.

Binocular loupes are used for professional purposes. Ophthalmologists, dentists, and ENTs cannot do without this device. When examining a patient, it is often necessary to consider the smallest details. The quality of the examination and subsequent treatment depends on this.

The use of the device is also relevant for household types of work. The devices are used in the collection of clockwork and small elements, the repair of microcircuits. The device is suitable for needlework. High optical performance lenses provide clear visibility and sharpness. Therefore, magnifiers are used during embroidery and knitting.

Characteristic

Special head magnifiers are widely used both in science and medicine, for example, they are very often used by neurosurgeons and ophthalmologists, and in everyday life, all because they are very comfortable and functional. After all, there are situations when we need to consider some small details, and at the same time, our hands should be completely free.In such a situation, of course, an ordinary desktop magnifier with a mount can help, but often its magnification capabilities are not enough, and it is also not very convenient to transfer it from place to place every time. This is where binocular loupes come to our rescue.

Such a magnifier is a magnifying glass in a plastic case, most often lightweight, a device is attached to the head using a special strap and a retainer, often they are made with illumination. Also recently, magnifying glasses began to be replaced by plastic lenses, which are in no way inferior, and sometimes even superior to glass.

The general characteristics of binocular lenses include:

• the field of view is the area that the eye can see through a given lens;
• the working distance of the lens is the distance at which the lens is clearly focused;
• depth of field is the range of distance over which an object or image remains in sharp focus;
• the magnification factor is the number of times the image is enlarged.

Selection rules

A magnifying glass is an indispensable assistant, but in order to work with it comfortably, before choosing a model of a particular design, you need to try to take into account the following important points:

• determine what the magnifying glass will most often be used for and how long they will have to use;
• what shape, size and configuration the magnifier should be;
• Do you need a backlight, what intensity and spectrum it should be;
• what magnification the magnifying glass should have;
• how the magnifier will be attached for the convenience of your work;
• what material the magnifying glass will be made of.

As practice shows, a magnifying device is acquired for long-term use and for performing specific tasks.

When deciding on the choice, do not forget to take into account the ratio of quality and price, and also pay attention to the service life of the product

Description of the forehead binocular lens

Head-mounted binocular loupes are modern medical devices that are designed to magnify a certain object several times during a surgical procedure. Also, the optical device illuminates the area of ​​interest without forming a shadow. The device can increase the resolution, luminosity, stereoscopic effect, thereby reducing the load on the organ of vision and increasing the speed, quality and efficiency of the doctor's work.

The binocular lens, which is attached to the helmet, provides a comfortable environment for long-term work. The distance of the magnifier between the pupils can be adjusted with a special handle attached to the helmet. The magnifier has a fairly good brightness, so you can inspect the investigated area for 5-6 hours without additional recharging. Working with a magnifying glass connected to the network is allowed without time restrictions.

One of the main advantages of an optical device is the ability to work only with a magnifying glass light source. It can be removed from the field of observation by hand without moving the illuminator. The service life of the medical device is guaranteed by the manufacturers and is at least 30 years. LEDs can work up to 50 thousand hours. The LED light source is characterized by low heat generation, reliability, wide spectrum, high quality and safety.

The medical device is widely used in various areas of surgery: vascular; orthopedic; maxillofacial; plastic; general; cardiac surgery; neurosurgery.

Doctors from public and private clinics conduct examinations of patients using a lens, since it can be used to examine the smallest details of an object and reveal hidden diseases, pathological disorders, deviations from the norm and anomalies.

Types

Magnifying glasses can be divided into types, which depend on the design features.

1. Magnification degree. For devices that enlarge small objects, there is a certain rule: with an increase in the measurement frequency, the viewing angle decreases, but at the same time the object in question gets closer. The optimal ratio of the magnification factor and the viewing angle is considered to be the magnification factor of the object from 5 to 7 times. Depending on the degree of magnification, magnifiers are subdivided into devices with strong or weak approximation.
2. Product design. A magnifying glass alone is not enough for the convenience of its use, and a certain holding structure is attached to it. Thanks to various design models, the magnifier has become very convenient to use. In retail chains, you can now find a wide variety of types of structures: on a bracket, on a flexible holder, on a stand, on a clothespin. There are long-handled magnifiers, headlamp options, table or floor models, cord magnifiers, keychain pocket magnifiers, and so on.
3. Equipped with lighting. To improve the quality of view and when working with poor lighting levels, an illuminated magnifier is used. LEDs are most often used for backlighting. Illuminated magnifiers are in great demand; they are used in medicine and cosmetology, radio engineering and microelectronics, in the jewelry industry, the banking sector, and in everyday life.
4. Lens material. Nowadays, lenses made of glass, plastic or acrylic polymers are widely used. The most budgetary option is a plastic magnifying glass, but this material is very unstable to mechanical stress and various scratches quickly appear on it. The most expensive and valuable lens material is glass. Of course, it will not withstand a fall from a height onto a solid foundation - a concrete floor or asphalt, but minor minor damage is not afraid of it. In the mid-priced category, there is an acrylic polymer that is more durable than conventional plastic, but inferior in quality to the properties of lenses made of glass.

Varieties

Optical loupes differ not only in terms of range and magnification characteristics. They are divided into types depending on the type of attachment.

Types of binocular loupe attachment:

• spectacle frame;
• special helmet;
• rim or hoop;
• metal frame.

A device in the form of goggles or a helmet is considered comfortable to use. Such magnifiers make it possible to correctly distribute the load. In addition, the glasses have special mounts for correcting eyepieces. This system allows several doctors to use the same frame with different visual acuity at once. Glasses can be easily exchanged for others thanks to convenient grooves in the base of the structure.

Helmet models look like a design without glasses. They can be worn directly over your own glasses. The device is adjustable in height and width. Inside, the design is equipped with soft pads, which eliminates the appearance of discomfort during prolonged wear. There are also models of helmets with protective lenses. The choice depends on the convenience and purpose.

Illuminated fixtures can be equipped with a flashlight in the middle or on a special visor.There are illuminated devices on the sides. If the fixture has multiple lenses, a flashlight can be positioned near each eyepiece. Also, these models have the additional function of adjusting the direction of the beam.

An important feature of models with flashlights is the location of the battery compartment. It does not make the structure heavier and does not cause discomfort during work

Tilt angle

In addition, to make the headlamp magnifier as convenient as possible, you should pay attention to devices with the ability to change the angle of inclination. So, if when using the device, the user has to lower the chin, this indicates an insufficient angle of inclination of the magnifier.

When, during the operation of the device, to form a clear, sharp image, you need to throw your head back - the angle of inclination is excessively large

So, if the user has to lower their chin when using the device, this indicates an insufficient angle of inclination of the magnifier. When, during the operation of the device, to form a clear, sharp image, you need to throw your head back - the angle of inclination is excessively large.

The ideal solution is a headlamp magnifier, which does not force the user to strain their eyes and neck while working.

Choice

Before choosing a type of binocular magnifier, it is worth considering all its advantages.

• Simplicity, convenience and ease of use.
• The ability to choose the option that will be useful to you in everyday life or in your work, since there are a lot of such varieties, there is a necessary item for everyone.
• Additional clarity of the desired image.
• A high-quality magnifier has a special coating that does not give glare, which means that the color rendition is excellent.
• Compactness of the device and low weight.
• Resistant to moisture and dust.

If you work in medicine and choose this magnifier, then you need to know the order of its selection.

1. First, determine the optimal working distance, that is, the distance between your eyes and the object you are looking at in Table 1.
2. Then, according to table 1, determine the required increase, depending on the specialty in which the work is carried out.
3. And at the end, decide on the type of the most head binocular magnifier that you need (type of attachment, illumination and the number of lenses in the set).

If you need such a magnifier for other work, then you need to choose the magnification factor of the lenses in a certain way.

• A magnification of 2.5 is the most common in use, as it has a large depth of field and a wide coverage of the field of view.
• The 3.5 magnification is used in very fine work, where a large depth of field and a wide field of view are not required. Usually these are works with very small details.
• The multiplicity 3.0 is something in between the first and second options. There is a very good magnification here and an average depth of field and an average field of view.

Thus, we can conclude that a binocular loupe is a very convenient device both in professional activities and in some domestic conditions. This device has a number of advantages compared to other types of magnifying devices, the main thing is to choose it correctly according to the above tips.
