Nikon Brightvue multicoating for up to 92% light transmission

Amazon.com

Nikon's renowned Brightvue multi-coating provides 92% light transmission for outstanding optical clarity.

One of the world's best-known optics companies, Nikon Sport Optics, has teamed with one of the nation's most respected sporting organizations, Buckmasters, to produce a riflescope line featuring high-quality optics.

Built to withstand the toughest hunting conditions, these scopes integrate shock-, fog-, and water-proof construction, as well as numerous other features rarely found on riflescopes in this price range. Nikon's Brightvue anti-reflective system of multicoated lenses provides over 92% anti-reflection capability for the high levels of light transmission and optical clarity necessary for dawn-to-dusk big game hunting. After the lenses are cut and polished, Nikon coats them with multiple layers of anti-reflective compounds. The compounds serve to boost light transmission, improve contrast to pull game out of its surroundings, deliver true color rendition and flare-free viewing, and enhance the overall image quality.

The brightest in its class, the Nikon Buckmasters riflescope has a proven track record of reliability, durability, and precision, making it a true hunter's workhorse. The scope is at home on nearly any hunting rifle, muzzle loader, or even rimfire, boasting a rugged, one-inch main body tube and ultra-high-performance lenses.

Amazon.com Product Description

The Nikon 6430 3 to 9 x 50 Buckmasters matte riflescope is a rugged, waterproof, shockproof and fogproof scope. Put through an advanced vacuum process that removes virtually all air and water molecules, the scope's tube is then filled with nitrogen and O-ring sealed. This process ensures that the Nikon 6430 will perform under the most stringent of field conditions without suffering any effects of fogging or condensation.

The precision-ground and polished optical glass is coated with Nikon's exclusive Brightvue coating that allows 92 percent light transmission, giving you super clarity and high resolution. Positive, audible, manual 0.25 MOA (Minute of Angle) windage and elevation adjustments eliminate reticle creep or backlash. The Nikon 6430 features Nikon's specially designed Nikoplex reticle that is composed of a thick outer crosshair that steps down to a finer crosshair at the center. This feature leads your eye to the point of focus and allows for quick, easy targeting.

The Nikon 6430 features an adjustable 3x to 9x magnification and a large, 50 millimeter objective lens diameter, giving the scope an exit pupil size of 15.1 to 5.9 millimeters, depending on magnification. A 3x magnification setting on this scope makes the image appear three times larger than with the eye alone with an exit pupil of 15.1 millimeters. At the 9x magnification setting, the exit pupil would be reduced to 5.9 millimeters. The Nikon 6430 is a full-sized scope with an adjustable magnification and exit pupil, making it an excellent choice for low light targeting as well as long distance targeting in fair light.

About Exit Pupil Size
The size of the exit pupil for a riflescope is determined by dividing the objective lens diameter by the magnification rating. The human eye pupil diameter ranges from 2 to 7 millimeters, depending on the amount of light. For proper light gathering potential, the diameter of the scope's exit pupil must be equal to or greater than the diameter of your eye pupil at the light level you will be using the scope. If you're working in low light, your exit pupil size will be of greater importance. With an adjustable 15.1 to 5.9 millimeter exit pupil, the Nikon 6430 3 to 9 x 50 Buckmasters matte riflescope is an excellent choice for hunting in low light or long distance hunting in fair light.
