The BARSKA® 15~45 X 60 Naturescape ED Glass Waterproof Spotting Scope features phase coated BAK4 prisms and fully multi-coated premium ED (Extra Low Dispersion) glass that provide you with views of exceptional clarity and resolution. Phase coating results in maximum resolution and optical quality by correcting or "phase shifting" the light that is reflected off the prisms and optimizing if for the scope's aperture size. Compared to conventional achromatic lenses, ED glass lenses minimize chromatic aberration and other forms of distortion resulting in higher resolution and contrast.
