The Nikon 8x56 Monarch 5 Binocular (Black) ;features ;high-transmission optics ;and a ;weather-sealed housing that deliver the image ;quality and ;reliability characteristic of ;Monarch series binoculars. ;This ;large-objective model ;from the ;Monarch ;5 lineup features 56mm objectives and the same ;premium, eco-friendly ;glass optics as the rest of the Monarch 5 binoculars. The lens system is made of lead and arsenic-free, ;extra-low dispersion (ED) ;glass elements, which efficiently transmit light through the optical channel and maximize image brightness. To ;complement the high-transmission ED lens system, Nikon equipped the 8x56 Monarch 5 with multicoated roof prisms that render a luminous view that is packed from edge-to-edge with ;sharpness and contrast. Phase-corrective prism coating aligns the incoming wavelengths of light, ;preserving ;color fidelity and detail; ;a highly-reflective dielectric mirror prism multi-layer coating ;maximizes light ;seen through the eyepieces. This range of optical technologies allows the Monarch 5 binoculars to produce lifelike colors and impressive brightness
