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.

The 2 inch DSP double side polished sapphire substrates can be manufactured from high quality optical grade Kyropoulos grown sapphire crystals.
high purity single crystal sapphire epitaxial substrate is suitable for direct epitaxial process, PSS process, ALN process and other epitaxial methods. It has the characteristics of uniform wavelength, high brightness and small STD. we can accept product customization for the technical specifications, and produce sapphire single / double polishing substrates with different external dimensions based on C (0001), a (11-20) and m (1100) crystal orientations, with notch or straight edge crystal orientations.
