Mid-Infrared Fiber Optics
Hollow Glass Waveguides

Data Sheet

2011 SPIE paper on hollow fibers


Fiber delivery of QCL
Output Beam Profile
 
Waveguides with reflective layer and thin-film dielectric coating applied using novel processes

Dielectric coatings can be optimized for specific wavelengths or for broad-band applications

 
    Configurations

    Single-Mode high beam quality for 8 m to 12 m

    Multi-Mode low loss for 3 m to 16 m

    Bundles for remote IR imaging / signal-collection

 
Key Features
