A: Sapphire monocrystalline optical crystal is the hardest transparent industrial optical material with Mohs 9 hardness, and it is recommended for all high-durability harsh environments with strict scratch, corrosion and pressure resistance requirements:
- Deep-sea underwater ROV camera domes, which need to resist deep-water high pressure and seawater corrosion;
- Coastal city long-term outdoor surveillance camera housings to avoid salt fog erosion and surface scratch damage;
- Unattended outdoor optical detection devices with years of continuous operation without frequent maintenance;
- High-precision wear-resistant optical windows and protective domes for industrial automation equipment.
