Sapphire Optical Windows

     Synthetic Sapphire is a single crystal form of corundum, Al2O3, also known as alpha-alumina, alumina, and single crystal Al2O3. Sapphire is aluminium oxide in the purest form with no porosity or grain boundaries, making it theoretically dense. The combination of favourable chemical, electrical, mechanical, optical, surface, thermal, and durability properties make sapphire a preferred material for high performance system and component designs. For various semiconductor applications, sapphire is the best choice in comparison with other synthetic single-crystals.

     Sapphire windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration. Sapphire windows will exceed all other optical materials in harsh environments, providing a better barrier between elements. Creator Optics can make various Sapphire Windows according to special requirements and drawings. All of these Sapphire Windows are available with high-precision polished surface, surface accuracy and parallelism.

Typical Sapphire applications for optical windows:
· Aerospace: - Sapphire is used for its durability and erosion/corrosion resistance, often in combination with the ability to withstand high heat while having a very broad transmission range.
Applications include:
· Windows - FLIR (Forward Looking Infrared) windows for sensors and other optics. Optical clarity over a broad spectral range combines with durability in this application.
· Windows - for erosion resistance in salt and blowing sand environments, sapphire is used in conventional windows and dome shapes in replacement of softer, more fragile IR transmitting materials.
· Countermeasures lamps - sapphire flash lamps are used in IRCM's (Infrared countermeasures). The high temperature performance of sapphire is combined with broad spectral range in this application.
Analytical applications: · Sapphire is used in analytical applications where combinations of high temperature, pressure, and hydrofluoric acid species are encountered. These applications need the survivability of sapphire, while often needing other properties such as favourable UV or IR transmission.
Medical applications:
· Sapphire is used in surgical systems for laser transmission and in contact with bodily fluids.
· Endoscope windows - sapphire is often used in endoscope windows due to its durability in contact with tissues and in sterilisation environments such as autoclaving .
Optical applications: · Sapphire is used for short and long wavelength applications (UV and IR) beyond the range where conventional optics performs adequately. High temperatures and hostile environments also necessitate the use of sapphire optics.
· Illumination windows - for very high brightness illumination, sapphire windows survive the very high heat while providing the broadest spectral transmission.
Watch industry: Sapphire is widely used for watch glasses.

     Creator Optics has over 15 years of experience in optical processing. We are also able to offer a variety of customized sapphire windows. Such as sapphire rectangular sapphire windows, sapphire T-step windows (round and Rectangular), all-surfaces-polished sapphire windows, sapphire conical windows, sapphire wedges and so on. In addition, we can make micro sapphire windows with a minimum diameter of 0.3mm and a thinnest thickness of 0.2mm and large size sapphire windows up to 300mm.
