I don't Know if it is the right place to post it but I will try.
Did anyone know what is the best way to increase the hardeness (bayer test) of the coating ?
Is it using ionic assistance deposition in each layer of coating during the depositio process, or using another layer between HC and the AR coat like essilor is doing?
thanks
regards
