68° Series Waterproof Eyepiece
Immersive Long Eye-Relief Views at 68°
Designed with advanced computer optical modeling and combinations of low-dispersion, high-refractive-index glasses, the 68° Series delivers high contrast and resolution across a wide, immersive field of view.
Long eye relief throughout the series makes for comfortable viewing sessions, even for eyeglass wearers, while the parfocal design keeps focus consistent as you swap between focal lengths.
Every eyepiece is argon-purged and pressure-tested in one meter of water for 30 minutes to guarantee a truly waterproof, fog-proof, fungus-resistant seal, and each ships with a removable, foldable soft silicone eyecup.
