- Huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods.
- Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas.
- This also maximizes the life of the internal coatings.
- Every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.
- All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
