It exists different AR coating. We divied ebteween normal AR coating and harder AR coating. We use the second one of rour U-models. Important to know is that the AR cueaitng is just a thin coating on the surface from the crystal. Also the strongenss of the R coating is softer than the crystal that’s why you havetwo different levels of hardness. If you “hit” against a door or something like that it can happen that the AR coating can get lost. Normaly this happens over years.
But optionally we can level down the AR coating, if this is an option for you.
