Five extra-low dispersion
(ED) glass elements and an aspherical element, arranged in a new optical design that minimizes chromatic aberration
There are also three strategically located ED (Extra-low Dispersion
) glass elements that work in combination with the aspherical lenses' elements to minimise chromatic aberration and ensure the ultimate resolution is captured.
The complex design features 22 lens elements configured in 16 different groups, including one Super ED (Extra-low Dispersion
) and two ED glass elements, all of which are working together to minimise chromatic aberration and ensure the ultimate resolution is captured.
Made of premium Japanese HOYA extra-low dispersion
glass and multicoated lenses, these binocs are guaranteed to perform ...
Integrating two aspherical lenses, two UED (Ultra Extra-Low Dispersion
) lenses and an ED (Extra-Low Dispersion
) lens, the lens system comprises 15 elements in 12 groups.
The specially coated, extra-low dispersion
lenses provide razor-sharp resolution and true-tolife color fidelity to help you pluck game from brushy environments.
Vortex uses High Density (HD) premium, extra-low dispersion
glass in the Razor, which enhances resolution and color fidelity.
The lens's construction includes 19 optical elements arranged in 14 groups along with an Extra-low Dispersion
element to minimize chromatic aberrations.
This 8-inch f/4 Newtonian reflector is paired with a four-element f/2.8 focal reducer and field flattener (made with extra-low dispersion
glass) to produce round stars across a 25-mm-diameter field.
The lens combines aspherical lens elements and ED (extra-low dispersion
) lens for high optical precision, offering high resolution and minimal chromatic aberration at all settings, from 28mm wide-angle to 560mm super telephoto.
In 2001, Nikon was the first manufacturer to offer the groundbreaking Digital ICE3 technology in its film scanners, as well as high quality ED (Extra-low Dispersion
) glass for sharp clear images and accurate color representation.
Realizing consistently high resolution across the entire frame, even at F1.8, the FE 135mm F1.8 GM boasts an innovative optical design that places XA (extreme aspherical) and Super ED (Extra-low Dispersion
) glass elements in the front group to effectively suppress all common telephoto lens aberrations.
