Nikon's Advanced Optical System The ProStaff 7S binoculars provide high-resolution images with extremely accurate color reproduction, thanks to Phase-Correction Coated Roof Prisms. Multilayer coatings, which provide an even higher light transmittance across the entire visible light spectrum, are applied to all of the lens and prism surfaces that transmit light. This minimizes the loss of light due to reflection, thereby ensuring a more natural, clearer view.
