ULTRAVID 7x42 HD-Plus

Leica Ultravid HD-Plus 7x42
Building on the success of the original Ultravid HD, Leica's 7x42 Ultravid HD-Plus Binocular adds improved technologies and materials to create an optic with bright and clear images across the entire field of view. The HD-Plus delivers enhanced contrast and true color fidelity, with virtually zero distortion, even in low-light conditions.
Leica upgraded the glass to specially formulated SCHOTT HT glass, which increases light transmission especially in the blue-violet light band, improves color fidelity, and enhances low-light performance. Scratch- and abrasion-resistant High Durable Coating (HDC) and hydrophobic AquaDura coating on the outer lenses protect surfaces and cause water and oil to bead off for easier cleaning and clearer vision. The roof prisms feature P40 phase correction and proprietary High Lux System (HLS) coatings. These coatings virtually eliminate chromatic aberration for enhanced color rendition and increased contrast.
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.
In addition to a brighter viewing image, the Leica Ultravid HD-Plus 42 binoculars also offer increased contrast performance in all viewing situations, and particularly in unfavorable light. The binoculars feature exceptionally high-quality lenses that reduce flare to an absolute minimum. This guarantees excellent colors and contrast, outstanding image brightness, clarity and optimum resolution of details. The shock-absorbent armoring protects the binoculars against damage while also providing excellent grip for safe and steady handling.
The essentials:
12 precise glass lenses of SCHOTT HT™ (High Transmission) for amazingly natural color rendition and increased brightness
Improved geometry of lens surfaces for never-before achieved edge to edge image sharpness.
High-temperature plasma deposition lens coatings for perfectly balanced light transmission throughout the entire wavelength range of visible light
New eyepiece design for longer eye-relief, nearer close focus, and wider field of view
