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 […]

Description

FlexiSpec® product line includes the latest generation of Transmission  fiber optic probes to be used with any spectrometer or photometer  in any part of UV –Vis or Vis – NIR spectra. Sapphire windows  allow to use Transmission probe  in wide range of liquids.

By request probe shaft can be  electrically heated to prevent moisture condensation on optical windows.

Stainless Steel or Hastelloy C22 schaft is suitable for the work in harsh environment.  Transmission  fiber optic probes are compatible with process-interfaces to ensure the cleaning and reaction monitoring in lab, pilot plant and industrial setup to  run process control.
