基于能量集中度的装调方法采用一套由可调谐激光器、积分球、平行光管和数据采集处理软件等组成的精细定焦系统，以确定 CO2探测仪1610 nm 通道光谱仪的最佳焦面位置并完成探测器的精确安装，以像元光谱响应曲线（ILS）的全高半宽度（FWHM）作为聚焦评价函数，通过调整探测器方位遍历搜寻该函数最小值并作为正焦的最终评价依据，进而完成光谱仪的精细定焦任务。定焦结果显示：探测器获得的光谱响应曲线平均半宽度为0.1281 nm，与理论值吻合良好。该系统不仅操作简单、结构紧凑且具有较高的定焦精度，也为光谱仪定标等后续工作提供了实验保障。

In order to establish the best focal plane for the 1 61 0nm channel of CO2 spectrometer and install the HgCdTe detector accurately,the fine focusing system,which consists of tunable laser,integrating sphere,col-limator and processing software,etc,is adopted in a assembly and adjusting method based on focus energy concentricity.The focusing evaluation function of the system is based on the full width at half maximum (FWHM)of instrument line shape(ILS).During the experiment,the orientation of the detector is adjusted search to the minimum value of the focusing evaluation function,and this minimum is as final evaluation basis of positive focal plane,and fine focusing works of the spectrometer is completed finally.The results show that the average value of FWHMof ILS is 0.1 28 1 nm,which coincides with the theoretical number.The focusing system is simple,compact and precise,which can provides experimental guarantee for the spectral calibration.
