Fiber optic spectrometer major determinant analytical performance

by:FOT     2020-06-28
Fiber optic spectrometer performance is a major determinant resolution fiber optic equipment spectrometer measuring tool, mainly used for measuring the ultraviolet, visible and near infrared and infrared light intensity of the instrument, measurement, high degree, flexible use, good reliability, etc. User functions are specific for fiber optic spectrometer understand? Small make up today is to introduce the function of fiber optic spectrometer, hope you can help to you. The choice of optical fiber grating spectrometer grating depends on the spectral range and resolution requirements. For the fiber optic spectrometer, usually in the 200 - nm - spectral range 2200 nm. Due to demand higher resolution can be hard to get broad spectrum scope; At the same time, the higher the resolution requirements, its luminous flux will be less. For low resolution and wider spectral range, 300 lines/mm grating is usually the choice. If the requirement is high spectral resolution, you can select 3600 lines/mm grating, or choose more pixels resolution of the detector. Fiber optic spectrometer slit narrow slit can improve the resolution, but less flux; Broad slit, on the other hand, can increase the sensitivity, but lose resolution. In the different application requirements, choose the right slit width in order to optimize the whole test results. Fiber optic spectrometer detector probe is in some ways determines the sensitivity and resolution of the optical fiber spectrometer, detector light sensitive area is limited in principle, it is divided into many small pixels for high resolution or divided into fewer but larger pixel for high sensitivity. Back light sensitive CCD detector sensitivity is usually better, to a certain extent, so it can get better resolution in the case of no sensitivity. Near infrared detectors due to high sensitivity and thermal noise itself, adopt the way of refrigeration can effectively improve the SNR of the system. Fiber optic spectrometer with filter spectral itself multistage diffraction effects, the filter can reduce the interference of multistage diffraction. Unlike conventional spectrometer, optical fiber spectrometer is coated on detector, this part of the function in the factory need to install in place. At the same time, the coating also has the function of antireflective improve the SNR of the system. The performance of optical fiber spectrometer is mainly determined by spectral range, optical resolution and sensitivity. For more than one parameter changes usually will affect the performance of other parameters.
