FUD article on whether the entire lens on Apple's iPhone cameras are made of Sapphire (no one ever said they were) or they are just covered with a very thin Sapphire cover. Quote from the article: "tests . . .show that Apple could be using a more cost effective sapphire laminate on top of regular glass." All the sapphire needs to do is protect the lens from ordinary, everyday scratching, not a laboratory grade scratch testing machine. The sapphire cover does that quite well. Properly formulated glass lenses have a higher index of refraction than does Sapphire so are a better choice to make lenses out of, otherwise there would be a lot of high end lenses made from transparent artificial sapphire because it is easy to make. However, there are not any companies that make lenses out of pure sapphire because doped glass, or even some plastics, are a better choice to bend light. — PING!
