FOMEI 8x56 LEADER PRO ED FMC, binocular

This first-rate binocular of DCF construction is equiped with optics produced by ED technology - Extra-low Dispersion. ED (EXTRA-LOW DISPERSION) TECHNOLOGY In the objective design, glass with Extra-low Dispersion is advantageously utilised.Upon passage of light through any material, it is refracted at an angle proportional to the properties of the optical material (index of refraction). Due to the fact that the index of refraction of the material is different for individual wavelengths of the impacting radiation, white light is split into the spectrum upon passage through the material. The white image is therefore split into a set of colourful images, which have a different size and focusing position. It is therefore impossible to focus an image ideally without a colourful - rainbow rim, which then has a crucial effect on the luminosity and edge sharpness of the objective. When using ED glass, the colour defects are minimised and a nearly ideal image is achieved. These unique properties are utilised by the new LEADER PRO ED scopes.
