Application Cases of Sapphire Windows in 3 Major Optical Instruments
Sapphire (Al₂O₃) is widely used in optical instruments due to its exceptional optical transparency, mechanical strength, and chemical stability. Its high transmittance, excellent thermal resistance, and corrosion resistance make sapphire windows a critical component in many precision optical systems. In addition, sapphire exhibits superior hardness (Mohs hardness 9) and low thermal expansion (≈5 ×10⁻⁶/K), which
