                                          1. Introduction Optical windows are critical components in systems where electromagnetic radiation must pass between environments without distortion or degradation. They are widely used in laser systems, infrared imaging, aerospace sensors, semiconductor equipment, and high-pressure environments. The choice of material directly affects optical transmission, thermal stability, mechanical durability, and system lifetime.
