Features: - Ø25.4*0.3-6mm Versions Offered
- Uncoated Wavelength Range: 150 nm - 4.5 µm
- Available with AR Coating for 1.65 µm - 3.0 µm or 2.0 µm - 5.0 µm on Both Sides
- Stable Performance over a Wide Temperature Range
Our Sapphire Precision Windows are available in 1/2" to 6" diameters. The uncoated versions are designed for applications in the 150 nm - 4.5 μm range. AR-coated windows feature anti-reflective coatings designed for 1.65 µm - 3.0 µm (-D) or 2.0 µm - 5.0 µm (-E1) on both sides. Uncoated sapphire provides exceptional surface hardness and a transmission range extending from the UV to the MIR. It can only be scratched by a few materials other than itself. The uncoated substrate is chemically inert and insoluble to water, common acids, or alkalis at temperatures up to ~1,000 °C. Our sapphire windows are z-cut so that the c-axis of the crystal is parallel with the optical axis, removing birefringence effects on transmitted light.HCH also offers precision windows fabricated from several other substrates for use in a large variety of laser and industrial applications. For our complete selection, see the Precision Window Selection Guide table to the right. We also offer laser windows, which have AR coatings centered around commonly used laser wavelengths, and Brewster windows, which are designed to eliminate p-polarization reflectance.| Precision Window Selection Guide |

Sapphire Characteristic:
Good transmission over the visible and near IR spectrum,
The optical transmission is high with little or no distortion of the transmitted signal.
High mechanical strength,
Temperature stability,
Wear resistance
Chemical inertness.
Application:
Air and Gas Analyzers/Monitors, Cryogenic View Ports, UV and IR Windows and Lenses, Detector and Pressure Cells, Bar Code Readers.
Sapphire has a transmission from 190nm to 5300nm and is very strong compared with other optical materials. Sapphire windows can be used at very high temperatures, up to 2000°C.
Sapphire has excellent strength and abrasive resistance which enables it to be used in the form of very thin windows and extremely harsh environments. Sapphire is often used for pressure windows or port windows where conditions are severe such as sandy, salty environments where a softer BK7 window would quickly scratch and become unusable.
