Not so long ago, professional dentists, jewelers, cartographers, electronic engineers began to widely use the illuminated head magnifier. In this material, we will try to consider the most pressing issues that arise when choosing such a specialized device.

Increase

Standard head magnifier has a magnification factor of 2.5 times. Such models are in demand not only in dentistry, but also in other areas of medicine. The specified increase is optimal not only for beginners, but also for experienced users.

Some fields such as electronic engineering and microsurgery require a higher magnification binocular head loupe. In devices from leading manufacturers, the specified indicator can exceed the standard parameter up to 6 times.

Focus

The head magnifier should be selected depending on the working distance and the range in which the image remains sharp. Devices currently on the market, working distancewhich is in the range from 250 to 520 mm. The choice of the optimal solution depends not only on the overall quality of workmanship that distinguishes the head magnifier, but also on the nature of the manipulation of the device and the needs of the user.

As for the depth of focus, you can determine the indicator by measuring the farthest and nearest point at which the image remains sharp. Functional head magnifier allows you to achieve the desired focus by changing the settings.

Field of view

This refers to the area that must be clearly seen during the operation of the instrument when performing a certain job. In order for a head magnifier to provide a wide field of view, it is worth paying attention to the products of reputable brands. The ergonomics of cheap models make the user's options rather limited.

Tilt angle

In addition to making the head magnifier as convenient as possible, you should pay attention to devices with the ability to change the angle of inclination.

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

The ideal solution is a head magnifier that does not force the user to overstrain the eyes and neck in the process.

Lighting

For pickingFor head loupes, LED lighting elements are predominantly used. In particular, coaxial lamps produce the most uniform white light that does not cause eye strain.

Head loupes used in dentistry are often equipped with yellow light filters. The impact of such rays on elastic composite materials does not cause their premature hardening.

However, even the brightest LEDs, located in the wrong position, can leave work areas unlit. To avoid such inconveniences, preference should be given to headlamps with lamps fixed in the area of the nose of the user.

Helpful tips

When buying a head magnifier, you should pay attention to the following recommendations:

1. First of all, you need to decide on the level of magnification. The smaller the setting, the clearer the image is when covering a wide field of view.
2. The choice of a magnifying glass according to the working distance should be made taking into account individual needs and conditions of activity.
3. The ease of use of a head magnifier largely depends on the type of attachment. It can be a standard hoop, an ergonomic frame or a helmet.
4. Extremely important when using a magnifier is the presence of built-in coaxial lighting, which is especially bright and able to form a clear focus.

Benefits

Head loupes have a whole host of advantages over hand-held loupesmagnifying devices. First of all, devices of this category free the user's hands. Illuminated devices are ideal for working with printed circuit boards, clockwork, fine woodcarving, embroidery.

The most functional devices open up ample opportunities for adjusting focus, changing the angle of inclination, and focusing. Some models are equipped with laser pointers, which allow you to focus on the right details as you work.
