Explore Scientific 92° LER is a family of professional glasses which, thanks to their huge field of view, large offset of the exit pupil and excellent optics, combine the comfort of visual observations with the highest quality of the image obtained.

Explore Scientific 92° LER 17 mm 2" is a two-inch eyepiece with a focal length of 17 mm and an apparent field of view of 92°. In order to ensure sufficiently high contrast and excellent detail, all lenses are covered with a full EMD™ multilayer coating (Enhanced Multilayer Deposition), and their edges were additionally darkened.

The eyepiece is closed in a waterproof casing resistant to half an hour immersion in water at a depth of 1 meter. The casing is also filled with dry argon, which not only prevents fogging, but also significantly extends the life of the optical system coatings.
