Vortex Viper 10X50 HD Binoculars

This updated 2018 version of the Vortex Viper HD 12x50 Binocular gets upgraded with a significantly wider field of view, angle of view, and interpupillary distance adjustment range from the previous iteration to make views more spacious and viewing through them easier and more comfortable for a wide variety of users.

Optically, this binocular benefits from proprietary XR anti-reflection fully multi-coated optics that maximize light transmission through the light path and improve contrast and color rendition across the entire visual spectrum. The compact roof prisms are dielectric coated. Phase-corrected coatings limit internal interference, light loss, and diffraction while maximizing light transmission through the prism system.

These features work together to produce bright, sharp, and clear high-contrast views with accurate color fidelity and crisp resolution. The powerful magnification is designed for observing large game at extreme distances such as in the wide-open spaces of the American West. Large 50mm objective lenses draw in generous amounts of light to offset the dimming that can happen with high-power optics and maintain bright and crisp images even when conditions are less than ideal.

Complementing the optical performance are construction details that allow the Viper HD to withstand the rigors of the trail. The optical tubes are argon filled and O-ring sealed to be waterproof and resistant to internal fogging if the weather turns or they take an accidental spill in a stream or puddle.

Protecting the optical components is a polycarbonate chassis that is lightweight and durable as well as resistant to the expansion and contraction that metal suffers from and which can lead to fuzzy views over time. Vortex includes a GlassPak binocular harness case that protects the optic when not in use while keeping it close to your body, preventing swinging and swaying as you move or climb over rough and rocky terrain.

Objective lens caps and a one-piece ocular rainguard protect the exterior lens surfaces. To keep the caps and rainguard safe during use, they are tethered to the body and strap, respectively. Optical Performance Powerful 12x magnification brings subjects in for close observations at extreme distances Large 50mm objective lenses help maintain image brightness at long range despite the high power and provide generous light-gathering capability for improved vision in challenging conditions Compact roof prism light path enhances performance while helping to keep the weight and bulk down Phase-correcting prism coatings eliminate internal interference to improve color and contrast Dielectric prism coatings boost internal prism reflectivity to greater than 99% to maximize light transmission through the prism with minimal loss and diffraction High-density (HD), extra-low-dispersion (ED) glass lens elements reduce chromatic and spherical aberrations for increased contrast and improved color rendition and sharpness without distortion across the entire field of view Proprietary XR anti-reflection fully multi-coated optics increase light transmission for accurate color fidelity and improved contrast and clarity ArmorTek exterior lens coatings resist scratches and abrasions while allowing oil, dirt, and sap to be cleaned off without leaving smudges or residue Wide 66 apparent angle of view helps to reduce the appearance of the distracting hand shake that is common when holding high-power optics such as this 288-foot field of view at 1000 yards Use and Handling Closed bridge configuration provides a solid platform for the internal focusing mechanism Large slip-resistant center focus knob is easy to manipulate in cold and wet weather or while wearing gloves Locking right eye dioptric correction lets you compensate for individual eye prescription for tack-sharp views 56-75 mm interpupillary distance range allows easy viewing by a wide variety of users Twist-up click-stop rubber eyecups for comfortable use with or without eyewear Tripod mountable with an optional adapter for hands-free use to reduce vibration and arm fatigue 16
