Leica Ultravid 8x50 HD Binoculars The Ultravid 50 series are ideal for viewing right into the depths of dusk due to optimized image per formance thanks to new high-definition lenses and Leica AquaDuraTM coating for greater visibility in poor weather conditions. Fatigue-free viewing even under poor light conditions. The 8 x magnification guarantees a steady sharp image without the need to constantly refocus.Previously the Leica Ultravid class had already impressed with its outstanding technical achievements and its superior optical quality. Now with the innovative Ultravid HD models with 50 42 and 32 mm objective diameters the Leica engineers have once again succeeded in setting new standards.Fluoride LensesWith the help of new fluoride (FL) glass in Leica HD models the color fidelity and contrast of images is further improved. 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 AquaDuraTMThe models of binocular and spotting scopes with the new HD lenses are now fitted with Leica AquaDuraTM a "hydrophobic coating" which with its water and dirtrepelling properties ensures 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 TransmissionAs a result of constant development of antireflex coating and reflective layer on the prisms it has been possible to increase the previously already very high level of transmission on all 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.Excellent Image Quality - Even in Awkwark Light ConditionsStray 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 TemperatureThe 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.
