The high-performance Explore Scientific 20 mm, a 1.25 "bezel with a wide 68 ° 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 6-element lens system Made of low dispersive, high quality glass, covered with multilayered patented EMD (Enhanced Multilayer Deposition) coatings, these coatings increase the transmission of light, provide the highest contrast and sharpness, and a flat image across the wide 68-degree In addition, the edges of the lenses have been blackened to further improve the contrast.These eyeglasses have an argon filling that makes them 100% waterproof, which prevents the internal haze formed inside the glasses and makes them easier to clean because liquid cleaners They are not able to get inside Optical system protects the glasses and guarantees their long life. 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.
