High-quality sapphire material has a series of characteristics such as high strength, high hardness, high temperature resistance, abrasion resistance,corrosion resistance, good light transmission performance (in the 170nm ~ 6000 nm), excellent electrical insulation performance, and good mechanical properties.' The chemical performance is very stable, free from acid and alkali corrosion. The hardness of sapphire is high, with Mohs hardness level 9, second only to diamond (level 10).
Round sapphire windows are respected for their outstanding characteristics, making them highly searched for in a multitude of optical and industrial ventures. Their remarkable toughness and resistance to scrapes make them most ideal for use in one of the most attempting of situations. In addition, their optical quality and passage are genuinely remarkable, making it possible for the flow of light with utmost sparkle and marginal distortion.
