摘要：为了对自主研发的凸面光栅成像光谱仪进行光谱定标，基于单色准直光定标法设计了一套由单色仪和平行光管组成的光谱定标系统。采用自行研制的光谱定标数据采集软件及数据处理软件对凸面光栅成像光谱仪进行了光谱定标及定标数据分析。定标结果显示：该定标系统结构紫、通用性强，具有较高的定标精度，其光谱范围大于400～800nm，光谐分辨率优于10nm，能够满足实际定标要求。

Abstract:A spectral calibration facility consisting of a monochromator and a collimator was estab-lished 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 ima-ging 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 bet-ter than 400-800 nm and spectral resolution is superior to 10 nm, which can satisfy the calibration need in practice.
Key words: imaging spectrometer; convex grating; spectral calibration; collimated monochromatic cal-
