Ultra high strength glass was born, and the lens was as hard as "steel"
scientists at the University of Tokyo developed ultra-high strength glass, which was as hard as "steel". This kind of glass is mainly synthesized from silicon dioxide mixed with alumina, and can be completely transparent, light and thin, with excellent optical quality and not easy to scratch through carbon dioxide laser and "aerodynamic levitation" technology. In the future, it may be used in cameras, even lenses or various lenses
in the near future, will your camera bulge more severely? Anyway, it won't scratch. At that time, it was estimated that the merchants selling UV mirrors in Hetian, which is mainly applicable to the bending experimental bridge film of hot-rolled ribbed reinforcement for construction, would be miserable.
