A high-performance, 24-inch, Scientific Scientific 24-inch, ultra-wide 82 ° field of view optical spectacle offers amazing viewing experience, using the latest computer-aided design methods to optimize its usability.The design is based on a 6-element lens system made from low dispersive, high quality glass, all covered with multilayered patented EMD (Enhanced Multilayer Deposition) coatings. These coatings increase light transmission, provide the highest contrast and sharpness, and a flat image across the wide 82 degree field of view In addition, the edges of the lenses have been blackened to further improve the contrast.These glasses have an argon filling that makes them 100% waterproof, which prevents internal hazards formed inside the glasses and makes them easier to clean because liquid cleansers they are not able to get into the libraries Optical system protects the glasses and guarantees their longevity. In addition, the glasses in this series have a soft deflection, I need an eye that provides the comfort of observation.

Argon that provides water resistance prevails over nitrogen once, due to the larger size of the molecule (more difficult to "escape" from the eyepiece), two, due to chemical inertness.

Each eyepiece is tested for leakage by immersion for 30 minutes in 1 meter deep water.
