Optical Performance

The Vortex Viper HD Produces bright, crisp images with superb detail and excellent contrast. All its glass surfaces are fully multi coated with XR anti-reflective lens coatings, still made by Vortex. This improves light transmission, resolution and contrast. Its optical system features phase-corrected and dielectric coatings on all prism surfaces which further enhance light transmission, improving color fidelity and resolution.

Vortex have made use of special HD extra-low dispersion glass at the objective end, reducing the degrading effect brought about by color fringing. This also allows for perfect viewing, ensuring that the colors always remain vibrant and clear at the optical sweet spot. All of these adds up to provide a fabulous viewing experience which hovers close to the upper echelons in optical excellence.

Field of View

The linear field of view is 319-feet at 1,000 yards. The 6.1-degrees angular field of view can be considered average for such a binocular. However, it still offers a better view of the activity, giving you an increased opportunity to see all action.


The Vortex Viper HD 10×42 is well-built, being O-ring sealed, filled with argon instead of nitrogen and fully waterproof. Purging of all the moisture from the inside eliminates the possibility of fogging or condensation on the internal glass surfaces when moving in different temperature extremes.

The special Armor-Tek coatings on the eyepiece and objective lenses cause any water on the lens’ surface to quickly bead and drop off. This implies you can keep using the Viper HD even in the worst weather conditions.
