Eyepiece FEP-25LER (20x/25x LER) (EDG)

The seven new eyepieces also offer exceptional EDG quality. Designed and developed with a particularly high level of innovation, they all feature a locking bayonet mount.

To create these eyepieces, Nikon developed solutions to complex optical design problems, such as combining a large field of view with a long eyepiece distance. In addition, an image field flattener lens system was used in these eyepieces to correct overall aberration and provide a sharp image even at the edge of the field of view. The result is a beautifully clear view.
