Product Overview
For those who know unforgettable moments don't happen by chance, Razor® UHD delivers the edge your once-in-a-lifetime opportunities deserve. The Ultra High Definition optical design features an improved optical prescription and index-matched apochromatic lens configuration, correcting chromatic and spherical aberrations to eliminate off-axis comas and improve colour and contrast beyond the Razor HD tier.
A genuine, meaningful difference from every other binocular in this range: the Razor UHD uses an Abbe-Koenig prism with a longer optical path for sharper image resolution, rather than the standard roof prism used across Triumph, Diamondback, Viper HD, Razor HD and Kaibab HD. Phase-correcting prism coatings and XR Plus fully multi-coated optics combine for maximum light transmission and the pinnacle of low-light performance.
Birders and close-observation users will appreciate the genuinely close 4.5ft focus distance. The ArmorTek exterior lens coating protects against scratches, oil and dust, and the lightweight magnesium chassis is argon-filled and O-ring sealed for reliable, durable protection against dust, debris, fog and water — flagship construction to match flagship glass.
