Nikon has developed eyepieces exclusively for MONARCH Fieldscopes. Each employs a new optical system, and a Field Flattener Lens Sysytem that delivers consistent sharpness and clarity across the entire field of view. Engineered to provide a wide field of view, MONARCH eyepieces also provide sufficiently long eye relief. When attached to a Fieldscope, each of the three new MEP eyepieces are waterproof*, ensuring safe use even during unexpected weather changes. This zoom-type eyepiece with a zoom range from 30x to 60x* realizes ultra-high optical performance. With an advanced optical design, it corrects image distortions while maintaining a wide field of view over the whole zoom range. What Mfg: Nikon
