The Vortex's line of Razor UHD Binoculars deliver spectacular optical performance from dawn to dusk. They come equipped with Vortex's exclusive UHD Optical System – an advanced optical design that significantly reduces chromatic aberration with enhancing color fidelity, edge-to-edge sharpness, and light transmission. The UDH Optical System is further enhanced thanks to the Abbe-Koenig prisim, which enhances optical quality, color fidelity, and light transmission even more. The Razor UHDs have also been outfitted with Vortex’s top-of-the-line XR Plus lens coatings for use in low light situations like early dawn or late dusk. In addition, the Razor UHD is tripod adaptable for extended glassing periods.
