Leica's 10x42 Noctivid Binocular represents the perfect combination of form and function in a single optic. It is designed with an array of complementary technologies to produce bright and clear color-neutral images, while fitting comfortably in the hand for long, fatigue-free glassing sessions. The Noctivid's performance starts with the use of Schott High Transmission glass with a 12-element lens configuration and their HighLux-System anti-reflection multi-coatings, followed by phase-corrected compact roof prisms.These features produce bright and clear high-contrast images with accurate color rendition across the entire visible spectrum. Internal baffles limit scattered light in the optical tubes which can affect clarity and contrast, while an innovative lens design and internal field flatteners ensure edge-to-edge clarity across the entire wide-angle field of view. The wide viewing angle and relatively high 10x magnification allow you to take in sweeping views while also giving you the ability to make detailed observations of distant objects. The wide viewing angle also helps to mitigate the common occurrence of disorientation that often accompanies high magnifications when using the optic on rolling seas or airborne platforms.Features:SCHOTT HT Glass and 12 Lens ElementsP40 Phase-Corrected Roof PrismsAnti-Reflection Fully Multi-Coated OpticsHighLux and AquaDura Optical CoatingsWide 64deg Apparent Angle of ViewNitrogen-Filled, Water and FogproofDual-Hinge, Open-Bridge ConfigurationMagnesium Alloy ChassisLarge Center Focusing KnobTwist-Up Click-Stop Eyecups
