The 50 mm Ultravids are ideal for viewing right into the depths of dusk. With optimised image performance, thanks to new high-definition lenses and Leica AquaDuraTM coating for greater visibility even in poor weather conditions.
The Leica AquaDuraTM coating ensures clear viewing even in the harshest weather. Even extreme cold cannot stop the rugged Ultravids delivering impressive viewing experiences. The new focusing mechanism uses high performance teflon discs with almost no lubricant to ensure consistantly smooth focusing - even at temperatures as low as -25° C, where many other binoculars would fail.
New definition of "Ultravid"
The Ultravid range has always impressed with its technical and optical performance standards. Now with the innovative new Ultravid HD series, with 50, 42 and 32 mm lens diameters, Leica are again setting new performance benchmarks.
With the help of the new fluoride (FL) lens glass, in each Leica HD model, both the colour fidelity and image contrast are further improved. Optical FL lenses are to a large extent made up of calcium fluoride. 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.
The Leica AquaDura coating is a "hydrophobic coating" which, with its water and dirt repelling properties, ensures clear visibility even in poor weather conditions. 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 anti-reflex coating and reflective layer on the prisms, it has been possible to increase the previously already very high level of light transmission by at least a further 3 %. The new Leica HD range now reliably combines an optimum degree of image brightness with a consistant level of colour fidelity.
Excellent image quality
To eliminate stray or false light effectively, Leica has developed a special software-simulation, which makes stray light visible in the processing phase. Using this technology in the construction of the new HD-models has ensured they are optimised via advanced housing design, better light absorbing paint, apertures and stray traps, such that stray light is almost eliminated.
Consistently smooth focusing - whatever the temperature
The mechanics of the Ultravid HD focusing mechanism have been further refined and as a result focusing is even smoother and remains free of play across the entire range. Optimised material pairings (e.g Brass and Aluminium) plus gliding discs made from extremely tough, high-performance plastic are used. In cold conditions conventional greased focusing mechanisms sometimes only work with difficulty and at higher temperatures they move too freely. In fact these focusing mechanisms can feel "sticky" at higher temperatures and there is even a risk that grease can escape and run on the lens. With the new Leica focusing mechanism these risks have been eliminated, working practically without lubricants.
