    Q&A

    Can you make windows out of sapphire?

    Sapphire is ideal for use as a window where high radiation resistance is required from the UV to about 5µm. It can be used to form doublet lenses with Silicon and Zinc Selenide for the MWIR (3 to 5µm).

    What is a sapphire window?

    Sapphire windows are optical windows made from synthetic sapphire, a single-crystal form of aluminum oxide (Al2O3). Sapphire is a hard, durable, and scratch-resistant material, which makes it an ideal choice for use in high-stress environments and applications where optical clarity is critical.


    A sapphire window is a transparent optical element made from synthetic sapphire crystal, which is a form of aluminum oxide (Al2O3). Sapphire windows are highly valued for their exceptional optical properties, including high transparency over a wide range of wavelengths, excellent hardness (second only to diamond), resistance to scratching and abrasion, and high thermal conductivity. These properties make sapphire windows ideal for various applications in industries such as aerospace, defense, electronics, and optics, where durability and optical clarity are critical requirements. They are commonly used as protective covers for sensors, detectors, cameras, and lasers in harsh environments where other materials might degrade or fail.

    Does sapphire glass shatter?

    Sapphire is extremely strong and scratch resistant – making it the top choice for a fine timepiece. While sapphire is the more expensive of the three crystal choices, it has its advantages due to the scratch and shatter resistance.

    Sapphire glass is highly resistant to shattering compared to other types of glass, thanks to its exceptional hardness and toughness. It is one of the hardest materials available, second only to diamond on the Mohs scale of mineral hardness. This means that it is highly resistant to scratches, abrasion, and impacts, reducing the likelihood of shattering or breaking under normal conditions.

    However, while sapphire glass is very durable, it is not completely immune to shattering. Extreme forces or impacts could potentially cause it to fracture, particularly if it has imperfections or defects. Additionally, despite its hardness, sapphire glass can still be brittle under certain conditions, such as extreme temperature variations or sudden, intense impacts.

    Overall, while sapphire glass is highly resistant to shattering compared to regular glass, it is not entirely indestructible and may still break under extreme circumstances.
