Nikon WX 7x50 IF Binocular (Black)

WX binoculars 7x50 IF feature a super-wide field of view. Among Nikon binoculars that have been highly acclaimed by enthusiasts of astro, wild bird and nature observation across the world, generation after generation, the WX models are the most suitable for astronomical observation.

The WX binoculars realize a super-wide field of view providing a sharp image to the very edge of the periphery, which redefines the concept of what binoculars can be. They deliver an observation experience that far exceeds anything conventional binoculars can offer.

Employing eyepieces with superior optical performance, WX 7x50 binoculars achieve a super-wide field of view (apparent field of view of 66.6 degrees), while their Field Flattener Lens System compensates for a curvature of field across the entire field of view. This means that the sharp image obtained at the center of the field of view continues all the way to the periphery. Also, three ED (Extra-low Dispersion) glass elements employed in each tube compensate for chromatic aberration that can cause color fringing, realizing a contrast-rich and high-resolution view.

The WX series employs Abbe-Koenig prisms that feature total reflection on all surfaces, and provide a high light transmission rate. High-quality multilayer coating, featuring uniformly high light transmittance across the entire visible range, is also applied to all lenses and prisms to realize a clearer, more natural view.

Filter threads on objective lens parts allow a 55mm filter (P=0.75) to be attached. A WX binocular exclusive tripod adaptor TRA-4 and hard case are also supplied, for convenient and comfortable astronomical observation. These features combine to ensure that Nikon WX binoculars offer an unparalleled experience in astronomical observation.

Key Features

• Employing eyepieces with superior optical performance, a super-wide field of view (apparent field of view of 66.6 degrees) is achieved. Minimizing astigmatism and coma aberration, a sharp and clear image is realized, while the sharpness of the image at the center of the field is achieved all the way to the periphery of the super-wide field of view.
• The Field Flattener Lens System is employed for compensating curvature of field from the center to the very edge of the periphery. While realizing a super-wide field of view, it assures a sharp and clear image across the entire field of view.
• Using three ED (Extra-low Dispersion) glass elements in each tube, chromatic aberration that causes color fringing is compensated at the very edge of the field of view, realizing a contrast-rich and high-resolution image
• High-quality multilayer coating which features uniformly high light transmittance across the entire visible range, is applied to all lenses and prisms to realize a more natural, clearer view. It reproduces the colors of stars in the night sky with fidelity.
• Abbe-Koenig prisms that feature total reflection on all surfaces and have a high transmission rate are employed, for a brighter field of view
• Applying a phase-correction coating on roof (Dach) surfaces of Abbe-Koenig prisms, which compensates phase shifts of light when reflecting inside prisms, results in high-resolution and high-contrast images
• Optical design that realizes both a super-wide field of view and long eye relief. The super-wide field of view can be enjoyed comfortably from edge to edge, even by eyeglass wearers
• Lead- and arsenic-free glass is used for lenses and prisms
• Turn-and-slide rubber eyecups with six-clicks facilitate easy positioning of the eyes at the correct eyepoint
• Diopter adjustment ring with index for easier adjustment
• Waterproof structure that will not be affected if submerged in water to a maximum depth of 5m/16.4 ft for 10 minutes. (Under Nikon's testing conditions. Not designed for underwater usage.)
