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


    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

Excellent transmission across the whole Mid-IR spectrum from 3 to 16 m

Gaussian beam delivery

Simple, high efficiency coupling

Mode filtering

High damage threshold

Robust and flexible

No end reflections reduced laser feedback

No cladding modes reduced system noise
