The composition of fiber optic spectrometer as well as merits

fiber optic equipment spectrometer is a branch of the spectrometer, with small volume, fast acquisition spectrum, modularity and flexibility of the measurement system. Compared with large spectrometer through grating for different wavelength spectrum information, fiber optic spectrometer using the array CCD spectrum of different wavelengths information collected at the same time, the structure is more stable. Appearance of small, and because fiber optic spectrometer has been widely applied in industrial field. Optical fiber spectrometer is usually used as the signal coupling, coupling to the spectrometer will be metering spectral analysis. Due to the convenience of the fiber, the user can build spectrum acquisition system very flexible. Basic configuration including fiber optic spectrometer includes a grating, a slot, and a detector. These parts of parameters when spectrometer of choose and buy must elaborate. Spectrometer performance depends on the combination of these parts and calibration, the calibration after the fiber spectrometer, in principle, these parts can't have any change. 1, grating, grating choice 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. 2, slit: narrow slit can improve the resolution, but luminous flux is small; 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. 3, detector, detector is in some ways determines the sensitivity and resolution of the 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. 4, filter: because of the influence of the multistage diffraction spectrum itself, the filter can reduce the interference of multistage diffraction. Unlike conventional spectrometer, 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.
