Even with an uncontested heritage of all-conditions optical performance, the all-new 56mm objective MONARCH 5 further elevates its game with massive 56mm objectives and advanced low light brilliance. Nikon's ED glass lenses put it in a class of its own for battling darkness with sharp, high-contrast views. Long eye relief and tripod adaptable further its versatility. All MONARCH 5 binoculars are now built with Nikon's legendary ED (Extra-low Dispersion) glass lenses, which correct chromatic aberrations across the furthest limits of the visible light range and effectively compensate for color fringing. Even when observing objects that would make chromatic aberration the most apparent - such as adjacent whites and blacks - the images will maintain superior contrast and resolution thanks to the ED glass lenses. Manufactured as well as many other of its optics, with a high-eyepoint design. This provides a clear field of view for everyone, even when the user is wearing eyeglasses, with sufficient space between the user's eye and the eyepiece lenses. 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. Dielectric High-Reflective Multilayer Prism Coating, this technique boosts light reflectivity for the full visible range, which provides clearer whites and a sharper, brighter, and more natural vision across the entire field of view. .
