Custom Sapphire Optical Window 222mm×74mm×4mm Wear Resistance for Infrared windows
Blue Sapphire Optical Windows are primarily fabricated from optical-grade sapphire (α-Al₂O₃ single crystal). Here, "sapphire" refers not to natural gemstones but to high-purity, single-crystal aluminum oxide (Al₂O₃). Renowned for its exceptional hardness (Mohs hardness of 9, second only to diamond), outstanding wear resistance, thermal stability (melting point ~2030–2050°C), chemical inertness, and broad spectral transmission (0.2 μm–5.5 μm), sapphire is an indispensable material for extreme-environment optical applications.
A "window" typically refers to a flat, transparent plate that protects sensitive optical systems (e.g., sensors, lasers, detectors) from environmental hazards such as dust, scratches, chemical corrosion, or high-temperature/high-pressure conditions while maintaining superior optical transmission.

2. Ti:Sapphire Window For Laser Instruments Translucent Red Double Sided Polishing
1. Q: Where are sapphire optical windows commonly used?
A: Sapphire optical windows are widely used in high-temperature environments (e.g., industrial furnaces), laser systems, defense equipment (FLIR systems), and aerospace instrumentation due to their extreme durability and thermal stability.
2. Q: What makes sapphire windows better than glass?
A: Sapphire offers superior hardness (Mohs 9), chemical inertness, thermal resistance up to 2030°C, and broad transmission (UV to mid-IR), making it ideal for harsh applications where glass would degrade.
