Magnification
The most commonly used magnification is 2.5x. This applies to dentistry as well as other specialist medical areas. The 2.5 is equally suitable for novices and experienced users. With more experience, higher magnifications can be used, particularly for micro-surgery. The complete range of HEINE loupes covers magnifications from 2x to 6x.
Working distance (x) / depth focus (y)
HEINE offers the ideal working distance for every application and user, from 250 mm to 520 mm. The optimum working distance is not based on the loupe, but on the size of the user and the type of treatment.
The depth of focus for loupes is very simple to determine: You measure the closest and furthest distance in which an object can be seen in focus. The advantage of HEINE loupes is that, due to an extremely high depth of focus of up to 290mm, you can choose the working distance which is best and most ergonomic for you – regardless of your size.
Field of view
HEINE loupe systems have two considerable advantages: An extremely large and balanced field of view as well as ideal positioning of the oculars in front of the eye. Only flip-up systems like those from HEINE offer this large field of vision whilst simultaneously taking into account the ergonomic requirements of a loupe system.
High-quality optical magnification offers many advantages during treatment. Along with a considerable improvement in the sharpness of the image, you will also experience healthier, ergonomic body posture.
HEINE high-tech optics, fitted with achromatic lenses, give incomparably clear and brilliant images with no colour distortion. The high quality image in all HEINE systems is the result of the best optical components, manufactured by HEINE, allowing exact and individual adjustment of the optics. Our exclusive coating system ensures great results for a brilliant and bright image.
When choosing a magnification system, it is important to consider several factors. The two most important points to remember are optical performance and ergonomics.
Ergonomics
The declination angle is the angle between the line of sight in the normal eye position and the line of sight given by the user’s lowered eyes. If the user has to rest his chin on his chest, the declination angle of the loupe used is too small. If the user has to look down too far or tilt his head back, the declination angle is too large. The ideal declination of the head is achieved when the neck and eye muscles are as relaxed as possible.
Comfort is no problem for HEINE loupe systems. The adjustable declination angle and our extraordinary optical quality avoid strain on the neck and eye muscles. Weight is an important factor here; loupes and frames, including the coaxial LED lighting, are extremely light and therefore comfortable to wear, even over longer periods of time. The secret is that the weight is distributed evenly by the modern S-Frame.
Optical quality
HEINE loupes offer the brightest image of all comparable binocular loupes of this type. Our optics are enhanced by a special anti-refl ection coating. This multiple coating reduces the light refl ection to around 0.3 %. The result is as clear as it is satisfying. The alignment of the achromats or prisms is adjusted for optimum performance, resulting in extremely sharp images and a field of view which is free of distortion right to the edge – as well as an excellent depth of focus.
Coaxial lighting
With HEINE LED lighting, you will be working with 100 % coaxial, white and homogenous light. For dental applications, a yellow filter can be used, preventing premature hardening of composite materials.
Not all blessings come from above: Even an extremely bright and well positioned ceiling light may cast a shadow during some examinations. Only an additional coaxial light, i.e. fitted between the eyes, allows shadow-free lighting of, for example, a cavity.
