Fiber optic spectrometer is an instrument that uses fiber optic technology and optical principles for spectral analysis. It is mainly used to measure the light intensity in the ultraviolet, visible, near-infrared, and infrared bands, and is widely used in fields such as chemistry, biology, and environmental monitoring.
Fiber optic spectrometer is an instrument that collects the measured light source through optical fiber and performs spectral decomposition and analysis on it. Simply put, it can decompose "light" into components of different wavelengths and tell you how strong each wavelength is. The characteristics of fiber optic spectrometer are its miniaturization, high sensitivity, fast response speed, and the ability to flexibly perform remote sampling and online analysis through fiber optic probes.
constitute
Light source: generates light signals, commonly used types include white light sources, lasers, etc.
Fiber optic: transmits optical signals to ensure signal stability and reliability. Fiber optic materials need to be selected according to the working band, such as high hydroxyl fiber for ultraviolet/visible light band and low hydroxyl fiber for near-infrared band.
Spectral system: Splitting light to measure different wavelengths of light. Common components include gratings and interferometers.
Detector: converts optical signals into electrical signals, commonly used types include photodiodes, photomultiplier tubes, CCD detectors, etc.
Data processing system: processes the electrical signals output by the detector and converts them into spectral data.
Application field
Chemical analysis: Used for spectral analysis and component detection of chemical substances, such as quantitative analysis, color measurement, and radiation measurement.
Biomedical: Used for spectral analysis and disease diagnosis of biological samples, such as fluorescence spectroscopy and Raman spectroscopy analysis.
Environmental monitoring: used for spectral monitoring of environmental parameters such as atmosphere and water quality, such as water quality analysis and oil detection.
Materials Science: Used for material characterization and composition analysis, such as coated glass testing and semiconductor testing.
Food safety: used for food ingredient and quality testing, such as crop quality analysis.
Industrial field: used for LED detection, sorting, laser wavelength analysis, imaging and lighting, sensing equipment, etc.
