Day of Photonics 2026

By Stanislav Perevoschikov

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

By Stanislav Perevoschikov

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 […]
