SWAROVSKI Optik NL Pure 10x42

The Swarovski NL Pure 10×42 is a premium roof-prism binocular designed for birdwatching, wildlife observation, and demanding outdoor use. Its 10x magnification and 42mm objective lenses provide detailed views with a 399 ft field of view at 1,000 yards. Swarovski’s SWAROVISION technology incorporates field-flattener lens elements to support sharp image definition across the viewing field, while specialized optical coatings help maintain color fidelity and high contrast.

The optical system delivers 91% light transmission, and the 4.2mm exit pupil supports effective viewing in varied daylight conditions. An 18mm eye relief accommodates many eyeglass wearers, while the 7.6-degree actual field of view offers a broad viewing area for tracking birds and other moving subjects. The central focusing system and 2m minimum focus distance also make the binoculars useful for observing nearby details as well as distant wildlife.

The NL Pure 10×42 features a magnesium housing, inert-gas filling, and waterproof construction rated for submersion to 4m. Its compact dimensions of approximately 158 × 131 × 71mm balance a full-size optical system with a carefully shaped body designed for comfortable handling. With a weight of approximately 850g, this model is suited to serious nature observers who prioritize premium optical performance and a wide, immersive view.
