THE FIRST CHOICE OF ORNITHOLOGISTS AND DISCERNING NATURE LOVERS
Product Properties
- Extra-large field of view: High-quality, super wide-angle optics, combined with a 42 mm lens diameter, ensure optimal clear viewing, even at dusk.
- Apochromatic optical system: Fluoride-containing ELD lenses ensure exceptionally true-colour, high-luminosity and high-contrast image reproduction. At the same time, colour fringing at the edge of images is reduced to a minimum.
- Light transmission of over 90% thanks to fully multi-coated optics.
- Flat Field Vision: High edge sharpness thanks to a smoothed image field.
- High brilliance thanks to phase-corrected BaK-4 prisms featuring dielectric mirror coating.
- Particularly hard-wearing thanks to an impact-resistant magnesium housing.
- Water- and dirt-repellent objective and eyepiece coatings guarantee clear vision at all times.
- Waterproof and nitrogen-filled.
- Spectacle eyepieces also provide those wearing (sun)glasses with an optimum field of view.
- A stable tripod thread ensures steady viewing at all times.
- In addition to a 10 year warranty, Warranty Plus* is also provided.
