                      1. Introduction In modern optical engineering, especially in extreme environments such as aerospace, underwater exploration, defense systems, and high-speed sensing, traditional optical glass is increasingly being replaced by synthetic sapphire domes. This shift is not simply a material substitution, but a structural upgrade driven by demands for higher hardness, thermal stability, and environmental resistance.
