Taking its place at the top of Nikon's flagship series, the powerful 10x42 Monarch HG Binocular is engineered with complementary technologies to produce an optic that is built to perform in low-light conditions and in the harshest conditions. First is the use of lead and arsenic-free extra-low dispersion (ED) glass in the lens elements to correct chromatic and spherical aberrations. Next are phase-corrected and dielectric coated prisms which further limit internal light loss and diffraction, and improve image contrast. The optical path is fully multi-coated with anti-reflection coatings that increase light transmission, image contrast and sharpness, and provide true color rendition. Finally is the use of Nikon's field-flattener system, which eliminates the distortion common at the lens edges for crisp details along the far periphery of the wide field of view. This all translates to bright and clear high-contrast images with accurate color across the field of view - especially in low-light conditions such as dawn and dusk, and heavily overcast skies.
The chassis is built with a short bridge design which presents more gripping surface, and helps to reduce the overall weight. Made to live a life outdoors, the optical tubes are nitrogen-filled and O-ring sealed to make them not only fogproof when moving between extreme temperature changes, but also waterproof. The exterior has textured, rubberized panels that protect against knocks and drops, and offers a slip-resistant grip for sure handling in cold and wet conditions. Nikon includes tethered objective lens covers and ocular rainguard to ensure they cannot be lost easily and are ready for use at a moment's notice.
