Focusing In order to focus the binocular or spotting scope on an object, optical groups within them have to be shifted with
respect to one another. When focusing is accomplished by moving a lens group inside the instrument, this is referred to as intern-
al focusing. This enclosed construction and the additional nitrogen filling make it possible to design watertight binoculars and
spotting scopes that guarantee a uniformly high imaging performance that lasts for the entire life of the instrument, even under
the most adverse climatic conditions. The particularly short focusing travel from near to infinity on Leica binoculars (on the Ultra-
vid models it amounts to slightly more than a single turn) the observer can always keep the subject in sharp view very quickly.
Leica HDC™ (High Durable Coating) HDC™ is the proprietary designation of a rub-proof and transmission-enhancing multi-
layer coating process developed by Leica that consists of 7 to 10 exceedingly thin layers, depending on the type of glass to which
they are applied. HDC™ signifies high light transmission combined with high resistance to scratches and environmental effects,
which translates into brilliant images and durability, even in intensive outdoor use.
For the requirements of intensive use in nature, high-performance binoculars and spotting scopes must be able to withstand
extreme mechanical demands over long periods of time. To that end, the optical and mechanical components are mounted in the
body of a Leica binocular or spotting scope in such a way that they cannot shift. The tolerances for the mechanisms used for
moving lens groups are set at a very minimum and they are strictly enforced. An important parameter in the selection of the right
materials is their extreme longevity, and they must also safeguard the highest degree of precision. Leica meets these require-
ments with proven and durable materials such aluminum die-castings and steel. In order to achieve a significant reduction in
weight – for instance in the Ultravid models – Leica also employs special high-tech materials such as magnesium and titanium.
In the planning of all these aspects, the longevity of the products and the benefits for the customers are always in the forefront.

Leica innovations and patents
The proficiency for innovations at Leica is demonstrated not least by the countless patented problem solutions that are valued
by customers and that evolved in close cooperation and coordination with international innovation teams composed of users in
a great variety of fields.
Leica HighLux-System HLS™ The HighLux-System HLS™ combines extensive mechan-
ical steps for the reduction of stray light (such as light traps, matte black lacquer, etc.)
and an especially developed mirror layer for prisms into an optimally tailored system.
The HighLux-System HLS™ is used in Duovid and Ultravid binoculars. The highly reflect-
ive dielectrical mirror layer consists of 42 extremely thin individual layers that produce
a degree of reflection of more than 99.5 %. This system makes it possible to increase
transmission, contrast and sharpness significantly – the observer gains an extremely
bright, natural pictorial impression with neutral color rendition.
