HLS® ist the HighLux-System, used in Duovid and Ultravid binoculars. It can significantly increase transmission, contrast and sharpness. It is a system of mechanical measures for the reduction of stray light (for example baffles, anti-reflective paints) in combination with special reflective coating of prisms.

High Definition means highest quality, both in terms of optics and mechanical measures. It features special fluoride glass materials and includes AquaDura® coating. Ultravid HD focusing remains fully functional, even in extreme temperatures – with unerringly smooth action.

What is the exit pupil?

The bright, circular field that can be seen by looking through the eyepiece from a distance of around 30 cm is called exit pupil. It is calculated by dividing the front lens diameter by the magnifi...

The bright, circular field that can be seen by looking through the eyepiece from a distance of around 30 cm is called exit pupil. It is calculated by dividing the front lens diameter by the magnification. A sign of quality: the circular field should always be perfectly round with sharp edges.

What means ER i?

ER stands for extended eye relief. ‘i’ is for ‘illuminated’, designating illumination suitable for twilight use.

EHR stands for Equivalent Horizontal Range, a helpful parameter for shots in mountainous terrain. A special Leica algorithm always takes at least one ballistic trajectory into account when calculating the EHR, providing results far more accurate than the ‘rifleman’s rule’.

What is the Automatic power-off function?

Via acceleration and position sensors, this intelligent technology switches off the illuminated dot when the rifle is not in shooting position. It also extends battery life considerably.

Its water and dirt repellent properties guarantee a clear view – even in unfavourable weather conditions. AquaDura® improves viewing comfort and the increased abrasion resistance protects the precious optical elements even more effectively against damage.

What is APO chromatic aberration correction?

APO stands for the apochromatic correction achieved by the use of special glass containing fluoride. This increases sharpness and contrast and prevents undesirable colour fringing.
