The high-performance Explore Scientific 6.7 mm spectacle in a 1.25 "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 sunglasses have a nitrogen (or alternatively argon) filling that makes them 100% water-resistant, counteracts the internal haze formed inside the glasses and makes them easier cleaning because liquid cleaning agents are not able to get to the internal ? inside the lens. This protects 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. | • Construction: | 7 optical elements | | • Focal length: | 6.7 mm | | • Field of view: | 82 ° | | • Diameter of binding: | 1.25 " | | • Output: | 14 mm | | • Anti-reflective layers: | FMC | | • Weight: | 227 g |
