What is a headband magnifier? Tips for choosing
Not so long ago professional dentists, jewelers, cartographers, electronic engineers started to be widely used magnifier headband with lights. In this article we will try to consider the most pressing questions that arise when choosing such a specialized device.
Standard headlamp loupe has the magnification of 2.5 times. These models are in demand not only in dentistry but also in other areas of medicine. This increase supports optimal not only for beginners but also for experienced users.
For some areas, such as electronic engineering and microsurgery, required binocular headband magnifier with higher magnification. In devices from leading manufacturers specified higher standard parameter up to 6 times.
Magnifier headlamp should be chosen depending on the working distance and the range in which the picture remains sharp. Currently on the market are the device, the working distance which is in the range from 250 to 520 mm. the optimal solution depends not only on the overall quality of manufacture, which is different headlamp magnifier, but also the nature of the manipulation device and user's needs.
With regard to depth of focus, to determine the parameters by measuring the far and near the point at which the image retains sharpness. Functional magnifier headlamp allows you to create the necessary focus due to the change in settings.
The field of view
This implies the area you want to see clearly during the operation of the instrument when performing a specific job. To headband magnifier provides a wide field of view, you should pay attention to the products of reputable brands. The ergonomics of the cheaper models makes the user experience quite limited.
In addition to headlamp magnifier highly convenient in operation, should pay attention to appliances with the ability to change the angle of inclination.
So, if you are using the device, the user has to lower the chin, it indicates a lack of an angle of inclination of a magnifying glass. When in the course of operation of the device for the formation of clear, sharp images you need to tip the head – tilt angle is excessively large.
The perfect solution is headband magnifier which does not force the user to overtax your eyes and neck in the process.
To complete the loop are mainly used headlamp led lighting elements. In particular, the coaxial lamp to produce the most homogeneous white light which causes strain eyes.
Headband magnifiers, which are used in the field of dentistry, often fitted yellow light filters. The penetration of such rays in elastic composite materials does not cause premature solidification.
However, even the brightest LEDs in the wrong position can leave unlit workspaces. To avoid such inconvenience, preference is a headlamp the devices with lamps, fixed in the nose of the user.
When you purchase a headband magnifier, you should pay attention to the following recommendations:
- First of all, you have to determine the zoom level. The lower the value, the greater the clarity of the coverage of the wide field of view.
- Select the magnifying glass according to the working distance should be tailored to the individual needs and conditions.
- Ease of use headlamp magnifying glass depends on type of attachment. It can be a standard Hoop, ergonomic frame or helmet.
- Extremely important when using the magnifying glass acts as a built-in coaxial illumination, which is characterized by special brightness and the possibility of formation of clear focus.
Headband magnifiers have a whole lot of advantages compared to manual magnifying devices. First of all, the devices this category, freeing the user's hand. Device with the backlight, ideal for working with printed circuit boards, clockwork, performing the finest of wood carving, embroidery.
The most functional devices offer great opportunities for focus adjustment, changing the angle of inclination, the guidance of field. Some models are fitted with laser pointers that allow to focus on the desired point during execution of work.
