Vortex 12x50 Viper HD Binoculars
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

* 16mm eye relief reduces eye strain to make for more comfortable viewing, especially over extended periods

* 4.1mm exit pupil will completely cover most pupils as they open and dilate in low light to ensure the whole scene remains in view without vignetting

Construction Details

* Lightweight and impact-resistant polycarbonate chassis

* Chassis material is temperature resistant, limiting the expansion and contraction that can occur with metal materials. preventing optical components from moving out of alignment over time

* Rubber armoring provides protection from bumps and impacts while offering a positive slip-resistant grip in cold and wet weather

* Argon-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions

* Tethered objective lens caps and one-piece ocular rainguard protect the lens surface without the fear of losing them when not in use

* GlassPak binoculars harness holds the optic close to your body to keep them safe and secure without swinging or hanging when moving or climbing over rough terrain Key Specs
