Optical aids have become essential tools in the daily life of dentists. For any type of intervention, these devices help practitioners to perform better. However, you must have the right information to be able to choose the most suitable equipment. For the best dental loupes this is important now.
The binocular loupes are practical to improve the efficiency of the care, but also for the comfort of the dentist in his work.
To optimize your choice
- Different magnifications are on sale ranging from 2.5x to 6.0x.
- Different models of optical aids
- Several models exist, but you must choose the material with which you feel more comfortable.
- Helmet, mount with optical system lift, optical system stuck on the glass of a traditional telescope, or optical system integrated into the glass. Several models are available.
- If each material has its own advantages, essential criteria must be taken into consideration to optimize your choice.
Indeed, there are so many manufacturers of binocular telescopes that it is not easy to find the right product. However, one important piece of information you need to remember is that there is a universal optical ruler: at equal working distance, the larger the magnification, the lower the width and the depth of field. In addition, you have to see if the manufacturer is reliable, because you may have similar fields for different magnifications for the same working distance.
- This is why it is necessary to opt for prismatic systems, also known as “Kepler”. This tool provides a total field without contour aberration. By using this prismatic system, you are sure to get quality images.
- In addition, powerful optical systems are preferred to have the best image resolution while respecting colors and ensure a perfect control of optical aberrations.
- In that it is the depth of field, it depends on the working distance and the magnification of the optical system.
The user is advised to seek advice with his optician and correct any visual abnormalities (nearsightedness, farsightedness, astigmatism and presbyopia) according to the chosen working distance.
Choose the right magnification
If you have just begun operating under optical aids, 2.5 x magnifications is appropriate. This magnification combines comfort and power and the large depth of field ensures easier chair movement.
Magnifications of 3.5 xs up to 6x are recommended for practitioners who are accustomed to working under optical aids. They are also more practical for practitioners who perform a more specific operation: aesthetics, surgery, microsurgery, endodontics.
A good working distance is reached when it is equivalent to the distance of the operator (distance practitioner eye / patient) for an optimal comfort.
Lifting optical system vs fixed optical system
Units with liftable optical systems are designed to operate as required with or without magnification.
The angle of declination and the bi-pupillary separation are variable. In addition, the viewing angle can also be adjusted to the work to be done. It is also simpler and faster for the optician to change the optical lenses during the correction.
