Sapphire lenses have excellent mechanical strength and hardness. With sapphire having superb thermal and chemical resistance and being scratch resistant, sapphire is a perfect choice for lens applications.

• High hardness - 9H ( second only to Diamond )
• Scratch resistance ( compressive strength 21000kg /cm²)
• Abrasion resistance
• High mechanical strength
• High temperature resistance (Melting point 2030°C)
• Good thermal stability
• High optical production rate
• Welcome to ask/inquire some details/another of any color and effect of coating and metallization.
