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 […]

Application Note: Comparing Compact NIR Spectrometers for Polymer Identification

Posted on: 
10 October 2025

How do you ensure rapid and reliable polymer identification in your process?

Near-infrared (NIR) spectroscopy is a powerful, non-destructive technology for quality control, recycling, and in-line monitoring. But with various compact spectrometers on the market, choosing the right one for your specific setup is critical.

Our new application note offers a direct performance comparison, using our Diffuse Reflectance Fiber Probe to analyze six common polymers. We investigated different spectroscopic methods to provide clear, actionable insights.

Key takeaways from our study:

Clear Discrimination: Both Fabry-Pérot and grating-based spectrometers can successfully discriminate between all six polymer classes.

Bulk vs. Granule: We found improved class separation in bulk measurements due to the averaging of scattering effects, a key consideration for in-situ analysis.

Performance Differences: While the Fabry-Pérot based spectrometer provided better class resolution in a simpler model, the grating-based system is often faster and better suited for rapid process control.

This research proves the feasibility of using compact spectrometers with fiber probes for robust polymer analysis.
