Hollow Silica glass Waveguides (HWG) design is a perfect option to transmit a low divergent IR-light of Mid IR-spectrum from 3 to 17μm. High performance HWG are produced with core diameters span from 500µm to 1000µm with double polymer jacket to secure a superior mechanical strength and high flexibility of HWGs.
Low optical losses at the selected spectral windows without Fresnel reflection enable a broad variety of HWG applications in Mid IR-range.
