Large sapphire windows provide excellent transparency and pressure resistance for underwater cameras, submarines, and oceanographic research equipment.
Used in aircraft sensors, missile guidance systems, infrared imaging devices, and protective optical domes.
Ideal for laser protection windows and optical transmission components due to their high damage threshold and thermal stability.
Applied in harsh industrial environments where optical clarity, wear resistance, and chemical durability are essential.
Suitable for spectroscopy, vacuum chambers, plasma diagnostics, and high-temperature observation ports.
We provide customized sapphire windows according to customer requirements:
We can produce circular sapphire windows up to 680 mm in diameter and rectangular windows up to 750 × 500 mm based on our 1000 kg sapphire boule growth capability.
