The parameters of the performance evaluation of fiber optic spectrometer have?

Fiber optic spectrometer due to its advantages of high accuracy, high speed, has become an important measure to spectrum used in the surveying instrument is widely used in agriculture, biology, chemistry, geology, food safety, chromaticity calculation, environmental inspection, medicine and health care, LED, semiconductor industry, petrochemical industry, etc. The performance of a spectrometer can use the following six parameters to reflect: 1. Spectral range: light signal can be 2 spectrometer detected wavelength range. Spectral resolution: distinguish small, zui wavelength can be spectrometer. 3. Sensitivity: can be spectrometer detected zui small light energy 4. Dynamic range: can be measured by spectrometer zui big and zui light energy ratio of 5. Signal to noise ratio: the ratio of signal energy level and noise level of spectrometer 6. Spectrum access speed: at a certain level of the incident light energy, production of a spectrometer to measure the signal and the time needed for the gain spectra for fiber optic spectrometer, the six parameters is closely related to each other.
