Round / Rectangular / Square Scratch Resistant Sapphire Anti - Reflective Coatings Available



Application of Sapphire glass :


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.
