Tele vue 17mm Nagler Type 4 (EN4-17.0)
Nagler Type-4 Eyepieces
Applying the experience of the Radian development to the 82° Nagler series, yielded more contrast, reduced pincushion, more true field, and longer eye-relief. With added eye-relief, the click-stop Instadjust eyeguard helps maintain proper eye distance and centration.
TeleVue Nagler represents unparalleled performance with an 82 Degree Field of View.
