Fourier Spectrometer Fiber SMA-IRF-01 Spectrometers Fiberock
Optical fiber material: Infrared silica fiber Connector Type: SMA905/FC/custom Fiber core count: Single-core
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.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
