What is a headband? Tips for choosing

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

Increase

The standard headlamp has a magnification of 2.5 times. Such models are in demand not only in dentistry, but also in other fields of medicine. This increase is optimal not only for beginners, but also for advanced users.

For some areas, such as electronic engineering and microsurgery, a binocular loupe magnifier is required with a higher degree of magnification. In devices from advanced manufacturers, this indicator can exceed the standard parameter up to 6 times.

Focusing

The headlamp should be selected depending on the working distance and the range in which the picture remains sharp. At present, devices are on the market, the working distance of which is in the range from 250 to 520 mm. The choice of the optimal solution depends not only on the overall quality of the manufacturing process, which is distinguished by the headlamp, but also on the nature of the manipulations with 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 in which the image remains sharp. Functional headlamp allows you to create the desired focus by changing the settings.

line of sight

Here we mean an area that must be clearly seen during operation of the device when performing a certain job. To ensure that the headlamp provides a wide field of view, it is worth paying attention to the products of authoritative brands. The ergonomics of cheap models make the user's capabilities quite limited.

Tilt angle

In addition, to ensure that the headlamp is the most convenient to use, it is worth paying attention to devices with the ability to change the angle.

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

The ideal solution is the headlamp, which does not force the user to overexert the eyes and neck in the process of work.

Lighting

For the configuration of headlamps, mainly LED lighting elements are used. In particular, coaxial lamps make it possible to obtain the most uniform white light, which does not cause eye strain.

Headless loupes, which are used in the field of dentistry, are often equipped with yellow light filters. The contact of such rays with elastic composite materials does not cause their premature hardening.

However, even the brightest LEDs located in an unsuccessful position are able to leave the working areas unlighted. To avoid such inconvenience, give preference to headlamp devices with lamps fixed in the nose of the user.

Helpful Tips

When buying a headlamp, pay attention to the following recommendations:

1. First of all, you need to determine the level of increase. The smaller the parameter, the greater the clarity of the image when covering a wide field of view.
2. The choice of magnifying glass according to the working distance should be made taking into account individual needs and operating conditions.
3. The ease of operation of the headlamp largely depends on the type of attachment. This can be a standard hoop, an ergonomic frame or a helmet.
4. Extremely important when using a magnifying glass is the presence of built-in coaxial lighting, which is distinguished by its special brightness and the ability to form a clear focus.

Benefits

Headlamps have a lot of advantages compared to manual magnifying devices. First of all, devices of this category free the user's hands. Devices with illumination are ideal for working with printed circuit boards, clockwork, performing the finest wood carving, embroidering.

The most functional devices open wide possibilities for adjusting the focus, changing the angle of inclination, and sharpening. Some models are equipped with laser pointers, which allow you to concentrate on the right parts during the work.
