The newly upgraded Black Hawk ED series of binoculars, the original 8x42, 10x42 based on the new 10x50, 12x50 specifications. The configuration is still luxurious, and the ED ultra-low dispersion lens with efficient light transmission is used to effectively reduce the refractive index of light, which means that it has smaller color difference and higher clarity, and the original appearance of the real object is restored to the maximum extent and the picture is clearer! BAK4 prism, shorten the light path, change the imaging direction to reduce light energy loss, improve brightness. The phase film on the roof surface reduces the color difference, the dielectric film on the reflective surface improves the transmittance, and the multi-layer coating on the lens surface further improves the brightness and clarity of the image.
24mm wide-angle eyepiece, super wide field of view, easier to find the target. Multi-stage spiral eye mask, large focusing wheel, anti-slip design, fine workmanship, precise focusing. The Black Eagle series telescopes are made of natural and environmentally friendly rubber, which is resistant to corrosion and can be used in high or low temperature environments. IP67 dustproof and waterproof, prevent dust from entering, can be soaked in a meter deep water for 30 minutes, stable and durable.
Black Hawk ED42 caliber binoculars recently focused only 1.5 meters, in the premise of ensuring the optical effect, reducing the length is very difficult, not only requires superb optical design capabilities, but also requires the use of higher quality lenses and more complex lens structure. Moreover, the color difference is very small, the clarity is very high, and the imaging contrast and brightness are very high. It is not an exaggeration to say that its optics can reach a high-end level. Especially suitable for observing flowers, birds and insects, landscape bird stargazing, highly recommended to everyone!
ED (Extra-low Dispersion) is a special glass that reduces the chromatic aberration of a long focus by dispersing light of different wavelengths. Different colors of visible light cause different refractive indices of the lens due to different wavelengths, so that the light can not converge on the same plane. Especially in long focal length telescopes, due to different wavelengths, red and blue light are easy to cause chromatic aberration, greatly reducing the sharpness of the image and the vividness of the color. By focusing all kinds of wavelengths of light on the same point, the ED lens greatly reduces the color generated by the telephoto, making the image sharp and sharp, strong contrast, and restoring the true color.
The whole telescope adopts FMC multilayer coating, so that the anti-reflection effect is more average in the entire visible wavelength range, and can obtain more true natural observation color.
