Fourier Spectrometer Fiber SMA-PI-IRF-01
Fourier-transform infrared (FTIR) spectrometers acquire material IR spectra using a transform from time/space to frequency domains, generally with high sensitivity and rapid acquisition. FTIR fibers deliver IR to samples difficult to access directly or return sample light to detectors. They allow flexible sampling of different regions or confined locations where the whole instrument cannot fit. Applications include chemistry, materials, biomedicine, and environmental monitoring. Fiber-linked instruments provide in-situ spectra under original sample conditions, valuable for live chemical-reaction/tissue studies. Selection: 1. Fiber type matches application/wavelength. 2. NA controls collection; higher NA gathers more signal but possibly more source background. 3. Diameter balances intensity/sensitivity and spatial resolution: larger gathers more but resolves less; smaller does the reverse. 4. Length balances loss and layout flexibility. 5. Bend resistance maintains stable transmission under bending/torsion. 6. Coatings/jackets match temperature, humidity, mechanical conditions, corrosion, and heat. 7. Connectors match instrument/probe interfaces for stable coupling. Balanced selection improves accuracy, sensitivity, and reliability.
