description

Sapphire optical fibers have a crystalline structure. These fibers transmit over a wide wavelength range from 0.75 to 3.5µm, and can be used at temperatures up to 2000°C.
They have too a very high hardness compared to quartz fibers.
Sapphire's durability and inert nature make the crystal fiber very useful for sampling optical signals in harsh environments. 

   
 
 

applications

These fibers can be inserted into the combustion chambers of internal combustion cylinders or turbine engines. In this way optical signal can be brought outside for spectral analysis.
Fuel constituents, contaminants, combustion products and combustion chemistry can be monitored in order to control fuel mixture, flow and timing.

Sapphire fibers can even be used in the fluorine plasmas used in semiconductor processing.

Other applications for this type of fibers are laser delivery for medical applications.
The Er:YAG laser produces a beam of wavelength at 2.94µm. This wavelength is very useful for certain types of medical and dental surgery.
Sapphire not only transmits this wavelength well, but have a laser damage threshold over 1200 Joules/cm², and is also biologically inert and autoclavable.

 
 
 

The Sapphire Fiber Advantages

• Biocompatible, nontoxic, USP Class VI approved
• High transmission from visible to beyond 3µm wavelength.
• Flexible : bend radius as low as 20mm for 150µm fiber diameter
• High strength : 400000 psi / 2.8Gpa
• High laser damage threshold : 1200 J/cm² and high melting point : 2035°C
