A high-performance, 3.7 mm Scientific Scientific eyepiece with an ultra wide 82 ° field of view offers an amazing viewing experience, using the latest computer-aided design methods to optimize its usability.The design is based on a 7-element design a lens system made of low dispersion, high quality glass, covered with multilayered patented EMD coatings (Enhanced Multilayer Deposition). These coatings increase the transmission of light, provide the highest contrast and sharpness and a flat image across the wide In addition, the edges of the lenses have been blackened to further improve the contrast.These glasses have a nitrogen filling that makes them 100% waterproof, which prevents the internal haze formed inside the glasses and makes them easier to clean because the liquid ones ? Cleaning agents are not able to get into the room inside the lens system, this 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.
