All-metal chassis, Nitrogen filledThe all-metal chassis ensures ruggedness and durability in the harshest elements, meaning the chassis won't crack in the extreme cold of winter, or disform in the intense heat of summer. Moreover, the chassis is filled with high-purity dry nitrogen gas to prevent internal fogging of lenses, protect the binoculars from water, and then to withstand all-weather environment.
Premium BaK4 PrismThe prisms inside the Desert 7x 50 Outdoor/ Astronomy Binoculars are made of high quality BaK-4 glass, phase coated, so that more light is reflected off their internal faces and passes through to the eye. Taken together, the fully multi-coated lenses and BaK-4 prisms maximize light transmission for the remarkably bright, highly detailed images.
50mm objective lensesAllowing more lights coming into the binoculars, and thus producing brighter and clearer images.
Ideal 7x MagnificationPowerful binoculars with 7x magnification, to get the detail you need when observing nature. It is the ideal power, increasing the reality 8 times, enough to see the objective but without shaking the image, and at the same time preserve enough field of vision.
Multi-coated Super HD Optical GlassesSuper HD Optical lens glasses minimize the chromatic dispersion and aberrations. Moreover, all air-to-glass surfaces on the Desert 7x 50 Outdoor/ Astronomy Binoculars Binoculars are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eyes and true colors can be revealed.
