Phase-Corrected Roof Prisms HDC and AquaDura Lens Coatings Nitrogen-Filled, Water/Fogproof Magnesium Alloy Chassis Protective Rubber Armor SCHOTT HT Glass Tripod Mountable.
The Leica Ultravid 50 HD-Plus binoculars provide exceptional contrast and outstanding image brightness that other binoculars with larger front lens diameters can hardly rival. Their fluoride lenses ensure optimum image clarity and resolution power. Thanks to their large front lens diameter, they are particularly suitable for observations at night and in the hours approaching darkness.
Leica Ultravid 50 HD-Plus binoculars are available with a magnification factor of 8x, 10x or 12x. With their ideal combination of high transmission and perfect contrast, the 8x50 DH-Plus models are truly excellent binoculars for use at night and in low-light. The 10x50 HD-Plus models offer high magnification for good detail identification and thanks to the large exit pupil they allow unique observation experiences even in the hours approaching darkness. Complementing the optical performance are uncompromising construction details.
To reduce user fatigue during long glassing sessions, the chassis is made of a lightweight yet durable magnesium alloy, with a titanium center hinge axle. The optical tubes are nitrogen-filled for fogproof performance and sealed to make the binocular submersible to 16.4' or 0.5 bar of pressure. Ergonomic thumb indents on the bottom of the binocular coupled with protective rubber armoring provide a comfortable slip-resistant grip. A lubrication-free focus system provides fast and precise focusing, with PETP-Discs to provide smooth movement throughout the broad operating temperature range.
