HEINE Binocular Loupes and illumination

Everything you need to know about binocular loupes. Ergonomic and optical factors.

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 ergonomics and optical performance.

Declination angle and 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 in combination with the retaining cord.

Optical quality

HEINE loupes offer the brightest image of all comparable binocular loupes of this type.

Our optics are enhanced by a special anti-reflection coating. This multiple coating reduces the light reflection 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.

The most commonly used magnification is 2.5x. This applies to dentistry as well as other specialist medical areas. The 2.5 magnification is equally suitable for novices and experienced users. With more experience, higher magnifications can be used, particularly for micro-surgery. The range of HEINE loupes covers magnifications from 2.5x to 6x.

Working distance and depth focus

HEINE offers the ideal working distance (x) for every application and user, from 250 mm to 520 mm. The optimum working distance (x) is not based on the loupe, but on the size of the user and the type of treatment.

The depth of focus (y) 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 290 mm, 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: A large and balanced field of view as well as ideal positioning of the oculars in front of the eye. Only flip-up systems with multiple adjustment options like those from HEINE offer this large field of vision whilst simultaneously taking into account the ergonomic requirements of a loupe system.

Coaxial lighting

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.

“Coaxial” design implies that the illumination beam is parallel to the visual axis, ensuring a completely shadow-free image and excellent illumination of difficult to see areas.

With HEINE LEDHQ illumination, you will be working with 100 % coaxial, white and homogeneous light. For dental applications, a yellow filter can be used, preventing premature hardening of composite materials.
