Wonderful vision at a glance

With all-weather brightness and clarity, combined with ED extra-low dispersion glass lenses, good fully coated optics, and high-coated BAK4 prisms, the Oonica Black Hawk telescope can collect more light and produce brilliant color authenticity. Waterproof, shock-resistant, and rubber protective layers are ready for any possibility. Even in the worst conditions, with an Oonica Black Hawk telescope, your vision will be clear at a glance!

1. Product Features:

ED Extra-low Dispersion Lens: ED (Extra-low Dispersion) low-dispersion lens is a special glass that disperses light of different wavelengths to reduce the chromatic aberration caused by telephoto. Different colors of visible light have different lens refractive indices due to different wavelengths, making it impossible for light to converge on the same plane. Especially in telescopes with long focal lengths, due to different wavelengths, red and blue light are prone to chromatic aberration, greatly reducing the sharpness of the image and the vividness of the color. ED lenses can actually focus all wavelengths of light on the same point, greatly reducing the color produced by telephoto, making the image sharp and vivid, with strong contrast, and restoring the true color.

BAK4 multi-layer prism coating: BAK4 is a glass with a higher refractive index than BK7, which can effectively improve the light transmittance, enhance the observation effect of the telescope, and make the viewing clearer and more vivid without distortion. The contrast is higher and the image is sharper in the dim light environment at night.

Level 7 nitrogen-filled waterproof: There are more sweat stains in outdoor activities and summer and rainy weather. The Oonica Nighthawk series telescopes can achieve level 7 nitrogen-filled waterproof, and can withstand a 30-minute 1-meter water depth test under certain conditions, allowing users to fear no wind and rain.

Master craftsman modern design: Oonica Black Hawk 8x42, 10x42ED binoculars are designed to be lightweight and highly durable. The anti-slip design on the side of the mirror body makes it easy to use and very textured, not easy to damage; the overall design is ergonomic.

Application areas: outdoor tourism, outdoor adventures, sports events, concerts, power inspections, forestry surveys, security police, police inspections, industrial inspections, maritime observations, archaeological research, railway line selection, land and resources surveys, etc.
