Product Description
9H Transparent 0.5-200mm Domed Sapphire Lens Glass for Watches
Properties of Sapphire Glass:A synthetic sapphire crystal or “glass” is actually not glass at all. It is a very hard, transparent material made of crystallizing pure aluminum oxide at very high temperatures. Synthetic sapphire has the same hardness as natural sapphire gemstones, but without the colouring agents that give the gems their various hues. When it is heated, the synthetic sapphire forms round masses, that are then sliced into pieces with diamond-coated saws. These disks are then ground and polished into watch crystals. (One reason sapphire crystals are relatively expensive is that the tools required to cut and polish this extremely hard material are very costly.) Sapphire (whether natural or synthetic) is one of the hardest substances on earth.
Our Sapphire Precision Windows are available in 1/2" and 1" diameters. The uncoated versions are designed for applications in the 150 nm - 4.5 μm range. AR-coated windows feature anti-reflective coatings designed for 1.65 µm - 3.0 µm (-D) or 2.0 µm - 5.0 µm (-E1) on both sides.
