Sporting an ultra-wide field of view, long eye relief, and comfortable exit pupil—all in a compact magnesium housing—the Swarovski 10x42 NL Pure Binoculars are the middle magnification entry in the series, striking the perfect balance between power and handling, making them ideal for mid- to long-range applications.

The NL Pure also employs extra-low dispersion (HD) glass elements and a range of proprietary optical coatings that, when combined with its other performance features, creates a set of glasses that delivers impressive image quality and durability. In keeping with its tradition of high-performance optics, Swarovski uses highly reflective roof prisms and fully multicoated fluorite-containing HD glass lenses to deliver superior image quality. A field-flattener lens system complements the glass and coatings to keep the edges of the view crisp and sharp. The resulting views are rich with detail and saturated with lifelike color with exceptional contrast and resolution.

In addition to its high-transmission optical system, Swarovski also equips the NL Pure binoculars with a range of design elements that improve the handling experience. A re-engineered bridge and focus system provide smooth movement in a short configuration, so you have more of the optical tubes to grip. Covering the magnesium-alloy housing is Swarovski's iconic rubber armoring that provides impact protection and a positive grip where they are needed most. The housing is nitrogen-filled and O-ring sealed to be resistant to internal fogging and waterproof to a depth of 13 feet. Additional features like tethered front and rear caps, soap and brush cleaning kit, carrying case, and neck strap round out the thoughtful details that make the NL Pure stand out.

Optical Performance
•High 10x magnification allows for detailed observation of distant subjects
•42mm objective lenses draw in the light required to extend its use in challenging conditions without being too bulky or heavy
•Compact roof prism light path keeps the optical tubes thin for easier handling and packing
•Field-flattener lenses eliminate spherical aberration & edge distortion and correct off-axis comas & astigmatism for crisp and sharp images across the entire field of view
•HD Optical System: Fluorite-containing glass virtually eliminates chromatic aberrations to enhance color fidelity and brightness
•SWAROBRIGHT, WAROTOP, SWARODUR coatings
•Ultra-wide 70° apparent angle of view greatly reduces the appearance of distracting hand shake while presenting sweeping views of the scene in front of you—providing an immersive and near panoramic observational experience that requires very little head movement to see everything
•Spacious 399-foot field of view at 1000 yards
