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.
*Eye piece is not waterproof on its own. It is only waterproof once attached to a Nikon Fieldscope.
