About sapphire glass
SAPPHIRE CRYSTAL (sapphire glass) generally refers to synthetic sapphire, generally used in the manufacture of the watch glass.
It is resistant to wear with tungsten titanium alloys and high-tech ceramics. but sapphire materials can wear resistance and
withstand the strong impact, and some of the same or higher hardness of the material (e.g., millstone, sandpaper, nail, granite,
concrete wall, and floor, etc.) so sapphire glass are not likely to scratch the surface of these materials.
Sapphire Optical Components are used in a variety of applications requiring high durability or broad spectral ranges, including semiconductor, FTIR spectroscopy, or FLIR imaging.
Sapphire, which is the second hardest crystal, features a variety of attributes that are ideal for use in harsh environments, including extreme surface hardness, high thermal conductivity, high dielectric constant, as well as a strong resistance to a variety of chemical acids or alkalis. Compared to many standard optical materials, Sapphire Optical Components offer thinner designs, along with transmission ranges from 0.15 – 5.5μm for optimum performance in the ultraviolet to the MWIR.
