Sapphire Optics

Endoscope Sapphire Window

for endoscopes Applications

High-hardness 9 Mohs, outstanding scratch resistance and chemical stability

Material: Optical grade single Sapphire crystal (Al₂O₃)

High transparent to wavelength of light between 0.3 μm (UV) and 5 μm (IR)

Widely used for high-temperature, chemical-resistant, and optical applications

Great transmittance, about 80%-90% in the visible light spectrum (approximately 400-700 nm)

Extremely high melting temperature (2030 °C)

Customized by design artwork

The purpose of a metallized sapphire window is to allow the optic to be soldered or brazed into place within a metal housing. Metallized, or solderable sapphire windows are commonly used in endoscopes and other hermetic brazing applications.

Metallized sapphire windows can better withstand the harshness of today's more aggressive autoclaves, as well as chemical and plasma sanitation systems.

The endoscope is used very bad environment, needs the high-temperature sterilization before using. It needs very high hermetic to prevent the moisture intrusion detected system, the moisture would affect the optical image clarity and service life. The endoscope sapphire window components than 5 * 10-12 PaM3/S, which can resist high temperature sterilization.

Notes

Anti-reflection coatings are also available at your specified wavelength.

Sapphire transmits ultraviolet light, but sometimes exhibit fluorescence when subjected to powerful ultraviolet sources. For this reason, they are best suited for use with visible to infrared wavelengths.
