Sapphire Optical Windows 2-100mm Thickness Ideal Materials for Harsh Conditions
Product Introduction:
A sapphire optical window is the ideal window material for many UV and IR applications because it can transmit so far into the UV Diameter 300mm Sapphire Optical Windows Clear Color 1mm - 100mm Thickness 0 nd IR bands. With its thermal and chemical robustness, a sapphire window can be exposed to extreme plasmas and temperatures, far greater than any other material, and continue to transmit high powered UV, visible and IR for years with no degradation. These properties make it an ideal material for UV/VIS/IR sensors, IR surveillance and recon and broad band inspection equipment (especially when abradants are involved).
Product Highlights:
Hardness and wear resistance: Sapphire optical windows with Mohs hardness up to 9 (Knoop ≈ 1370–2000 kg/mm²), maintaining surface finish and transmittance in sandy, salty, and abrasive environments and reducing image degradation and maintenance frequency.
Chemical inertness: Sapphire optical window is highly resistant to most strong acids/strong bases (except hot caustic alkalis), suitable for high‑purity, hygienic, and corrosive media settings.
Broadband transmission: Sapphire optical windows’ intrinsic transmission covers about 200 nm–5.5 μm; in practice, 330–5500 nm is commonly available, enabling multi‑band or broadband front‑end protection.
High‑temperature and pressure resistance: Sapphire optical windows with stable structure and optical performance up to about 1000°C, enabling thin windows under high pressure differentials for high‑pressure, vacuum, deep‑water applications.

Q&A:
Q: What is a sapphire window?
A: A sapphire window is an optical viewport made from single‑crystal aluminum oxide (Al2O3), used to isolate environments while transmitting light. It is not glass but a crystalline material, and it remains transparent from the deep ultraviolet (UV) through the visible and near‑infrared (NIR), typically to about 4.5–5.5 μm, depending on thickness and coatings. Sapphire’s extreme hardness (Mohs ~9), high melting point (~2030–2045°C), chemical inertness, and strength make it a rugged choice for harsh-duty optical ports.
Q: What is the hardness of a sapphire window?
A: Sapphire windows made from single‑crystal Al2O3 have a Mohs hardness of 9, the same as ruby. This ranks them just below diamond (10) and moissanite (~9.25), making them highly resistant to scratching in demanding environments. For context, common optical glasses are typically around 5.5–7 on the Mohs scale.
Q: What are the best AR coating options for sapphire windows?
A: Best AR coating options for sapphire windows in the 3–5 μm range.
