IRsweep in a collaboration with Pfizer and art photonics, have investigated the possibility of using very long mid-IR fibers in a spectroscopic setup.
These are the world’s longest mid-IR fibers ever used for spectroscopy.
IRis-F1 dual comb mid-IR spectrometer from IRsweep with a laser spanning the 1200 –1290 cm1 spectral range was coupled with 10m long ATR Mid-IR fiber probe from art photonics (Berlin, Germany).
