12x50 ED Glass Nitrogen-filled Waterproof Monocular BAK4 Prism Astronomical FMC Coating Powerful Telescope Traveling
¡¼The Main Functions¡½
1.ED(Extra-low Dispersion) glass is built in the Binocular. ED glass minimizes the effects of the secondary spectrum. Comparing to achromatic lenses, and ED glass reduces chromatic aberration to a remarkable degree.
2.BAK4 has a high refractive index and lower critical angle than other materials, which means it transmits light better with less light being lost due to internal reflectionsuch as from internal bubbles trapped during the manufacturing process.
3.Fully Multi-coated Glass means multiple coatings on all lens surfaces. And all air-to-glass surfaces are anti-reflective multi-layer coated. Fully multi-coated lenses are typical of high-end optics.
4.100% waterproof internals to handle the most extreme weather conditions, ensuring you can watch uninterrupted views.
