사파이어 윈도우, 사파이어 광학 윈도우 및 사파이어 보호 윈도우: 정의 및 기술적 차이점
1. Introduction Optical windows are fundamental components in modern optoelectronic systems, serving as both transmission interfaces and protective barriers. In demanding environments—such as aerospace, high-power laser systems, deep-sea exploration, and semiconductor processing—the choice of window material critically influences system performance, durability, and reliability. Among various materials, single-crystal sapphire (Al₂O₃) has emerged as a preferred candidate
