The NEP-38W Zoom Eyepiece for Monarch Fieldscopes from Nikon is a fixed magnification eyepiece designed for the Monarch series fieldscopes. It provides 38x magnification with the 82mm Objective Lens Unit and 30x with the 60mm Objective Unit. As with all the optics that are part of the Hybrid Body System, the eyepiece is fully multicoated for maximum light transmission and limited light loss.

The eyepiece features Nikon's CicuLock mounting and locking system. A collet chuck secures the eyepiece by fastening it uniformly in all directions with minimal optical axis deviation. A ratchet mechanism facilitates easy attachment and detachment of the eyepiece. When attached to the Prism Unit, the joint and eyepiece are waterproof. Its twist-up eyecup enables comfortable use for eyeglass and non-eyeglass wearers.
