The Binocular of the Century
This is Where a Century of Innovation Takes You
Eyepieces feature unprecedented optical performance and a super-wide field of view. Apparent field of view of 76.4˚. Engineered to minimize astigmatism and coma aberration and provide a sharp and clear image, 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.
Field Flattener Lens System
A Comprehensive Optical System that Includes Your Eyes in its Design
With such a super-wide field of view, images in peripheral areas would typically become distorted and change noticeably as the binocular is panned. The WX’s unique optical design deliberately retains enough pin-cushion distortion to enable comfortable observation.
High-quality Multilayer Coating
High-quality multilayer coating, providing uniformly high light transmittance across the entire visible range, is applied to all lenses and prisms to realize a more natural, clearer view. The colors of stars in the night sky are reproduced with fidelity.
ED (Extra-low Dispersion) Glass
ED glass elements employed in each tube compensate for chromatic aberration that causes color fringing at the very edge of the field of view. Multiple ED Glass elements result in a contrast-rich and high-resolution image. All lenses and prisms are free of lead and arsenic, under the Nikon Green Procurement Standards.
These prisms, which feature total reflection on all surfaces with a high transmission rate, are utilized for a brighter field of view. Phase-correction coatings on roof (Dach) surfaces of these Abbe-Koenig prisms compensate for phase shifts of light when reflecting inside prisms, resulting in high-resolution, high-contrast images and a slim body design.
Long Eye Relief
Optical design that realizes both a super-wide field of view and long eye relief. Eyeglass wearers can also enjoy a full, clear super-wide field of view. Rubber eyecups are designed to be removed for cleaning eyepieces. Eyepiece frame is designed in a flat shape for easy maintenance of details.
Straight Helicoid Diopter Adjustment Ring and Turn-and-Slide Eyecups
The diopter adjustment ring employs a straight helicoid design. Eyepieces move back and forth in a straight line, and the lenses themselves do not rotate, ensuring the optical axis is not decentered during diopter adjustment. Turn-and-slide rubber eyecups with six-click adjustment facilitate easy positioning and click intervals become finer as the eyecups are extended, for easier adjustment by non-eyeglass users.
Waterproof and Fogproof Structure that Withstands Severe Conditions
Accessories that Support Comfortable Astronomical Observation
Comes with an exclusive tripod adapter TRA-4. 1/4-in. (ISO1222) tripod screw enables attaching to a tripod. WX binocular’s exclusive case is supplied for storing the _binocular and accessories.
