Product Description

Sapphire optical windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration. Sapphire, a single crystal form of Al2O3, is resistant to attack by strong acids due to its high dielectric constant. It has high compressive strength and a high melting point. It is also resistant to UV radiation darkening. Our sapphire optical windows are not coated, but a single layer coating of MgF2 on each surface of the window increases the single surface transmittance to 99% throughout the entire visible spectral region. Please note the SAW series sapphire windows are provided in random axis orientation by default and its birefringent nature could affect the polarization state of your application.
