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

art photonics GmbH offers a large variety of specially designed Reflection and Fluorescence Probes. Based on Bifurcated or Multi Channel Furcated Fiber Optic Bundles with ”Illuminating” Leg to carry light from a source to a sample – and “Reading” Leg to carry reflected light to a Spectrometer.

By request metal coating fibers can be used for the Illuminating channel to reduce cross-talk.

Our Reflection Fiber Probes are available with two, three or four fiber legs, and Round-to-Round (R/R) or Round-to-Line (R/L) design.
