A sapphire window is ideal for use under demanding conditions and in harsh, stringent environments. Sapphire is the hardest material in the world other than diamond, and exhibits resistance to many chemical acids and alkalis. It also has very good scratch resistance, a high dielectric constant, and high thermal conductivity.
Dongqiao Optics manufacture high quality sapphire windows and precision optical components, and because of sapphire’s high mechanical strength we are able to make these optical windows much thinner and with better transmittance than other dielectric windows. Uncoated sapphire transmits best between 170 nm and 5.5 µm. We are able to provide custom windows to meet any specification
