The Bushnell Engage binoculars are a best-in-class optic with industry leading features. The entire line is backed with the all-weather assurance of Bushnell's exclusive EXO Barrier lens coating that repels water, debris, oil and fog. The fully multi-coated optics offer maximum brightness and clarity, and they're housed in a lightweight and rugged magnesium chassis. ED Prime Glass and locking eyepiece diopter ensure razor sharp images every time.
The dielectric prism coating features reflectance that exceeds 99%/ By utilizing light interference, this coating assures high reflectivity across the full visible range and ensures high-color reproductibility allowing 92% light transmission.
ED Prime Extra-Low flourite glass delivers amazing color, resolution and contrast, and virtually eliminates chromatic aberration and color-fringing to bring out the most distinct details possible in low-light conditions.
P3C prism chase coating is a chemical coating applied to the prisms to enhance resolution and contrast for the brightest and clearest images possible.
The ultra wide band coating is an anti-reflection coating process that is customized for every lens element in the optical path, in order to allow the best possible light from the front glass all the way back to the eyepiece. The result? Optimum brightness and true color across the light spectrum.
All of the air-to-glass surfaces on Engage binoculars feature multiple layers of anti-reflective coating. Fully multi-coated optical systems deliver the brightest, highest contrast images with the least amount of eye strain because only a very small percentage of light is lost before it reaches the viewer's eye.
Lead-free glass means Bushnell used no lead in the class lenses or prisms. By using environmentally friendly materials, Bushnell is not only helping you see the outdoors in stunning clarity, they are doing their part to keep them beautiful.
