A high-performance, 24-inch, Scientific Scientific 24-inch Eyepiece with a wide 68 ° field of view offers outstanding viewing experience, using the latest computer-aided design methods to optimize its usability.The design is based on a low-level lens system 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 68-degree field of view. In addition, the edges of the lenses have been blackened to further improve the contrast.These glasses are filled with argon to make them 100% water-resistant, preventing internal hazards formed inside the glasses and making them easier to clean because liquid cleansers are not they are able to get inside the optical system o. It 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. | • Focal length: | 24 mm | | • Field of view: | 68 ° | | • Diameter of binding: | 1.25 " | | • Construction: | 6 elements in 4 groups | | • Retracting the output pupil: | 18.4 mm | | • Anti-reflective layers: | EMD / FMC | | • Water resistance: | yes, Ar | | • Weight: | 305 g |
