Sapphire Windows for Harsh and Vacuum Applications and More

Sapphire Windows are built of Synthetic sapphire feature remarkable properties of extreme surface hardness, high strength, scratch resistance, high temperature resistance, chemical resilience, and transmits wavelengths ranging from UV to Mid-Infrared. Sapphire optics window and sapphire components are often offered complete to client end use specifications including specialty coatings like BBAR, short or long pass, V, or double V coating designs, along with solderable metallization.
 

SAPPHIRE WINDOWS PROPERTIES

 

Optical Windows are applied as viewports to shield other components within an optical assembly, instrument or laser. In a variety of applications, optical windows are required to withstand harsh environmental conditions and offer high-levels of performance and dependability. You will be amazed by the several unique properties Sapphire window has which make it ideal material for applications such as:
 

  • Synthetic Sapphire, the single crystal form of Al2O3, is among the hardest materials (9 Mohs hardness). By way of its structural strength, it can be made much thinner than other conventional optical windows, with improved transmittance functioning.
  • Sapphire windows are suitable for the applications in high power because of high thermal stability and excellent thermal conductivity.
  • Sapphire windows are better resistant to considerably higher temperatures with zero degradation than most optical windows.
  • Sapphire Windows vividness will not go when exposure to UV light. 
  • Sapphire windows are outstandingly stable and resistant to strong acid.


So, typically Sapphire windows due to its sturdiness are used where high pressure, high temperature, high thermal loads, vacuum, scratch resistance, corrosion resistance, small coefficient of friction including optical and insulating properties are a factor. These windows more often than not need to work under harsh operating conditions, so hard AR coating is needed to resist it, and also it improves resistance to scratch. An antireflection coating is also applied for adequate transmission where it is required.

Sapphire pistons offer optimal concentricity and resistance to wear. Sapphire is less abrasive and provide maximal resistance to damage.

For Sapphire lenses, it is usually used for medical optics, laser optics, and imaging applications. These lenses display exceptional performance like mechanical, optical, thermal, and chemical toughness. These features make sapphire lenses suitable for aerospace or deep sea uses. COE Optics is leading sapphire lenses manufacturer with years of experience dealing in sapphire optical component manufacturing and have the capability to polish sapphire lenses with low coarseness, high surface quality and surface accuracy.

With several benefits Sapphire Tube is in high demand across the globe. Sapphire tubes made of synthetic sapphire hold unique combination of exceptional optical, physical, and chemical properties. Sapphire is one of the hardest minerals is nearly scratch proof. It has as high as 2030 °C when it comes to its melting temperature. Sapphire’s brilliant thermal conductivity and heat resistance make it ideal for high temperature applications. Applications for Sapphire tubes are numerous and are ideal material for wide range of industrial functions such as semi-conductors processing, test and analytics, and Lamps and Lamp Envelopes. Standard applications for test and analyses involving biological and chemical test analysis, Nuclear Magnetic Resonance spectroscopy, Mass spectroscopy, plugged tubes, Thermo-optic temperature measurement, and Inline Petroleum treating analysis. It is also applied as Plasma containment tubes, Process gas injectors, Thermocouple protection, Water treatment, and High intensity lamps.
