Hollow Glass Waveguides

Categories: , Tag:

Main features:

  • High transmittance in selected parts of 3 - 17μm range for customized applications
  • No Fresnel reflection at the end faces
  • Inner diameter spans from 500 to 1000μm
  • Double polymer coating for high flexibility

For more information see data and downloads available below.

Description

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.
