The Advantage of Leica AquaDuraTM

On The Coated Objective Lens On The Left, The Rain Rolls Off...... On The Right, It Stays

The Leica Ultravid Class Has Already Impressed, With Its Outstanding Technical Achievements And Its Superior Optical Quality.  Today, With The Innovative Ultravid HD Models With 50, 42 And 32mm Objective Lens Diameters, The Leica Engineers Have Once Again Succeeded In Setting New High-Standards -----

The Next Generation

Fluoride Lenses
With the help of new fluoride (FL) glass, in The HD models, the color fidelity and contrast of images is further improved to perfection.  Optical FL lenses are to a large part made up of calcium fluoride, a mineral with a crystalline structure. Unlike conventional optical lenses, this creates a very low level of dispersion (light scattering) and corrects aberration (imaging errors) significantly better. So as a result, the viewing experience is more natural and impressive than it has ever been before.

Imitating nature : Leica AquaDuraTM
Our HD Models Are Fitted With Leica AquaDuraTM, A "Hydrophobic Coating", Which Sheds Water From The Lens Surface, Ensuring Clear Visibility Even In Poor Weather Conditions.  As with the leaves of the lotus plant, droplets of rain simply roll off the lens, and, fingerprints and dirt particles are much easier to remove.  In addition, thanks to its increased abrasion resistance, Leica AquaDuraTM will protect your valuable lenses from damage even more effectively

Increased Light Transmission
As A Result Of Constant Development Of The Antireflex Coating And Reflective Layer On The Prisms, It Has Been Possible To Increase The Previously Already Very High Level Of Transmission On All Our HD Models By At Least A Further 3 %.  Especially in poor lighting conditions such as twilight, image brightness is crucial.  If you then optimize the coating, especially for its suitability at nighttime, with conventional lenses this is then only at the expense of color neutrality, which is a drawback for daytime viewing - the image can appear to have a blue tint. If you do it the other way round, the result can be a green tint.  The New Leica HD range now reliably combines an optimum degree of image brightness with a constant level of color neutrality.

Exceptional Image Quality - Reliable In Awkward Light Conditions
Stray or false light can significantly reduce the viewing experience.  To eliminate this effectively, Leica is taking a great number of steps which, in awkward sidelighting and backlighting situations in particular, ensure a high-resolution, clear image without any reduction in contrast or constraints due to milky fogging. Specially developed software simulation allows stray light to be seen during development stage. Consequently, thanks to an optimized housing shape, improved light-absorbing paint, apertures and stray light traps, the construction of the new HD models have been optimized to such a degree that stray light is (almost) no longer of any significance. Because after all, you cannot select the position of the sun when you are observing nature.

  Consistently Smooth Focusing - Whatever The Temperature
The Mechanics For The Ultravid HD Focusing Have Been Further Refined.  As A Result, Focusing Is Even Smoother And Remains Free Of Play Across The Entire Range.  Optimized material pairings and gliding discs made from extremely tough, high-performance plastic are used. In cold conditions, the conventional greased focusing mechanisms sometimes only work with difficulty, and at higher temperatures they move too freely. Furthermore, these focusing mechanisms can feel "sticky", and at higher temperatures there is even the danger that grease can escape and run on the lens.  With the optimized Leica focus, these risks have been eliminated.
