Binoculars LEADER FOR ED is designed for demanding users and professionals. Technology ED + lens coatings FMC - Phase coating ensures maximum sharpness and light transmition of optics in category High Resolution. Prisms made of material BaK4 also have a surface coating Phase. The design of optical system provides a wide viewing angle. Light transmition of Leader optics allows observation of even the most demanding conditions including light observations. The body of the binoculars is made of polycarbonate which is very strong but has a lower weight than aluminum. Binoculars is able to focusing from 2 meters!
Diopter adjustment is integrated into central focusing unit (see figure).
ED technology (Extra-low Dispersion)
With selected models of Fomei binoculars, the optical system is made using the so-called ED technology. This technology prevents the passing light to polarise the colour spectrum, which significantly increases the luminosity and edge sharpness of the output image.
