Sapphire Substrates Description
Sapphire substrates are ideal for use instead of glass substrates when optical transmission is required in the ultraviolet (above 200 nm) or infrared (below 5 μm) range. Low-temperature optical measurements will also benefit from the higher thermal conductivity of sapphire substrates, and they may also be used in high temperature environments up to 2300 K.
Detail & Parts
Sapphire Glass Properties
- Chemical Properties: Sapphire, a crystalline form of aluminum oxide (Al2O3), exhibits remarkable chemical resistance to acids and alkalis, including hydrofluoric acid. Its hexagonal lattice structure consists of Al3+ cations and O2- anions.
- Mechanical Properties: With a Mohs hardness of 9, second only to diamond, sapphire is highly scratch-resistant. Glass, in comparison, has a hardness of approximately 5.5.
- Optical Properties: Sapphire, though birefringent, is precisely cut along the C-plane to eliminate polarization-dependent birefringence for normally incident light. It offers excellent transparency to wavelengths between 200 nm and 5 µm, making it ideal for UV and near/mid-IR applications. In the visible spectrum, sapphire has a refractive index of approximately 1.76.
- Thermal Properties: Sapphire exhibits a high thermal conductivity of ~40 W/m.K at room temperature, nearly 50 times greater than that of glass and twice as high as stainless steel. Its thermal conductivity increases to ~10000 W/m.K at reduced temperatures, making it well-suited for low-temperature optical measurements. It can also withstand high-temperature environments up to 2300 K. Our sapphire substrates are polished to optical quality, with significantly lower RMS roughness compared to glass substrates.
