Swarovski 10x42 NL Pure Binoculars 

• Fluorite-Containing HD Glass Elements
• Field-Flattener Lens System
• SWAROBRIGHT, SWAROTOP, SWARODUR Coatings
• Ultra-Wide 70° Viewing Angle

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.
