| Popis: | A spectral calibration facility consisting of a monochromator and a collimator was established to calibrate the Offner imaging spectrometer with a convex grating designed by ourselves.The self-designed software for sampling and processing spectral data was used to calibrate the Offner imaging spectrometer and analyze obtained data.Calibrated results show that the calibration facility has a compact conformation,better commonality and high calibration precision,and its spectral range is better than 400-800 nm and spectral resolution is superior to 10 nm,which can satisfy the calibration need in practice. |
