Proprietary EMD anti-reflective multi-coatings ensure bright, high-contrast images with true color transmission across the entire wide field of view. To keep internal reflections to a minimum and improve contrast, the inside of the barrel is blackened, as are the edges of the lenses, to minimize the scattering of light within the lenses themselves. A fold-down rubber eyecup prevents stray light from leaking into the eye, further boosting contrast.
All eyepieces in the 82° Series are parfocal, so there will be little to no need to refocus when moving from one focal length to the next. This eyepiece features a textured surface for a sure grip when changing it out, and it is argon filled for water and fog proof performance when used in extreme temperatures and climates.
