Day of Photonics 2026

Today, 21 October, is the Day of Photonics. The date marks the day in 1983 when the General Conference on Weights and Measures fixed the speed of light at exactly 299,792,458 m/s. The European Photonics Industry Consortium (EPIC) started the Day of Photonics in 2014 to make the field more visible outside labs and companies. […]

Flexible CO₂ laser delivery at 10.6 µm: PIR fibers vs hollow waveguides

art photonics Technical Note 007 Both polycrystalline silver halide fibers (PIR) and hollow waveguides (HWG) from art photonics transmit up to 85–90 % of CO₂ laser radiation (10.6 µm) through a 1 m high-power cable. Choose a PIR fiber when the cable must bend, move or run long distances: a full 360° loop costs only […]

Hollow Glass IR-Fibers

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 IR-Fibers  (Hollow Glass Waveguides) design is a perfect option to transmit a low divergent IR-light of Mid IR-spectrum from 3 to 17μm. High performance fibers are produced with core diameters span from 500µm to 1000µm with double polymer jacket to secure a superior mechanical strength and high flexibility of HGWs.

Low optical losses at the selected spectral windows without Fresnel reflection enable a broad variety of HGW applications in Mid IR-range.
