Nikon Action Ex Extreme 7245
The Nikon 7245 Action Ex Extreme Binoculars keep you hunting in the most extreme conditions. The Nikon 7245 Action Ex Extreme 10x50 ATB Binoculars are bright, multi-coated binoculars, using high-resolution lenses and prism systems crafted from Nikons exclusive Eco Glass. This waterproof binocular can be taken to any weather conditions, rain, snow or even in large temperature changes. The Nikon 7245 Extreme ATB Binocular is not only waterproof but also fogproof and shockproof.
The BaK4 High Index Prisms of this Nikon Action Extreme 10x50 binocular combined with its multi-coated optical lenses,allows for ample light transmission,which delivers true color rendition and crisp and clear images in most lighting conditions. The Nikon Action Ex Extreme ATB 10x50 Binoculars feature Apparent Angles of view that exceed 60 degrees, making them true Wide Angle binoculars.
Nikon 7245 Extreme binoculars feature an all-metal chassis with lens fittings housed in a tough, lightweight polycarbonate body shell. The same with other Nikon All Terrain Binoculars, the EX is nitrogen-filled and O-ring sealed for total waterproof, fogproof and shockproof performance in any environment. The binocular bodies are ergonomically shaped, tripod adaptable and rubber coated for a non-slip grip, whether wet or dry.
True Wide Angle Binocular
The Nikon Action Ex Extreme ATB 10x50 Binoculars feature Apparent Angles of view that exceed 60 degrees,making them true Wide Angle binoculars.
Real field of view is the angle of the visible field, seen without moving the binoculars, measured from the central point of the objective lens. The larger the value is, the wider the viewfield available. For example, binoculars with a wider field of view are advantageous for locating fast-moving wild birds within the viewfield. This also applies when you search for small nebulas or a cluster of stars in astronomical observations.
Twilight Factor
The factor that has the greatest impact on resolution or image detail, will be dependent upon the amount of light available during the time of observation. During daylight hours, when your eye pupil size will be only about 2 to 3mm, magnification will be the principal factor in image resolution. At night, with the eye pupil dilated to 6 to 8mm, aperture size is the controlling factor. In twilight conditions both of these factors control resolution effectiveness and the twilight factor is the term that compares binocular performance under these conditions.
The twilight factor is calculated by taking the square root of the product of the magnification and the aperture. The twilight factor really affect the resolution of a binocular, the higher the twilight factor, the better the resolution of the binocular when observing under dim light conditions. For example, a 10 X 40 (twilight factor 20) would effectively resolve better under these conditions than a 7 X 35 (twilight factor 15.4) even though the 10 X 40 has a smaller exit pupil. Remember, however, that the twilight factor does not take into account the transmittance or quality of the optical system.
Dielectric high-reflective multilayer prism coating
This coating features reflectance that exceeds 99%. By using light interference, this coating assures high reflectivity across the full visible range, and ensures high color reproductibility.
The horizontal axis indicates the wavelength of light. The vertical axis indicates the reflectance of light. Binoculars' brightness is determined not only by the reflective mirror, but also by the total optical system such as the number of lenses and quality of coatings. A new body style provides unparalleled strength and ruggedness in a package that is comfortable to carry all day. With rugged rubber armor for added durability and a firm grip even in the worst conditions, Nikon guarantees every ATB to be 100% waterproof and fogproof.
