Sapphire step windows stand out as a specialty at Blue Box optics. Also known as T-Windows, these step windows excel in applications such as viewports, pressure, and vacuum situations. They are particularly well-suited as viewports for deep ocean vehicles, showcasing resilience to harsh saltwater conditions and debris, all while maintaining a thinner profile compared to traditional glass counterparts.

Optical windows utilized in high-pressure scenarios benefit from reduced thickness, and sapphire step windows deliver on this front. With a MOHS hardness of 9, second only to diamond, sapphire transmits light in the range of 190nm to 5000nm, making it an excellent choice for UV applications and mid-wave infrared.

While round sapphire optical components are typically the most cost-effective, rectangular windows can also be produced, often cut from round stock. At Blue Box optics, we possess the necessary machinery to create custom-shaped windows as well, ensuring flexibility in meeting diverse requirements.

The substrate of the sapphire optical window consists of synthetic sapphire crystal (Al2O3). Synthetic sapphire, a crystal ranking second only to diamonds in hardness, manifests as a single-crystal form of pure and transparent Al2O3. Its exceptional mechanical, optical, physical, and chemical properties position sapphire as an ideal material for designing and implementing high-performance systems. In comparison to other optical materials, sapphire stands out as the optimal choice for a broad spectrum of demanding environmental applications.

1. Aerospace: Sapphire windows find extensive use in aerospace equipment and instruments owing to their impeccable durability, corrosion resistance, high-temperature resistance, and broad spectral transmission range.

2. Sapphire flash lamps: Renowned for high-temperature resistance and low thermal expansion, sapphire serves as a protective window for robust lamps and flashlights, ensuring scratch resistance and preventing bursting.

3. Analytical instruments applications: In scenarios where the analyzed gas or liquid is highly corrosive, sapphire windows prove invaluable due to their corrosion-resistant properties. Moreover, their excellent transmittance across a wide spectrum from ultraviolet to infrared makes them widely applicable in analytical instruments.

4. Medical equipment applications: The outstanding durability of sapphire windows renders them indispensable in various medical applications, including laser medical instruments, laser beauty instruments, and endoscopes.

5. Optical applications: With the extensive spectral range of sapphire crystals, sapphire windows can be employed in a myriad of optical applications, spanning from ultraviolet to infrared. Their mechanical and physical properties confer an advantage over optical windows made from alternative materials.

6. Illumination applications: The heat resistance of sapphire windows makes them ideal for use as protective materials in high-brightness lighting applications.

7. Watches and industrial instruments: Sapphire windows serve as protective covers for watches or gauges, offering resistance to scratches, robustness, and a guarantee against bursting.
