摘　　要：限于常规波长定标的局限性,构建了高分辨率紫外-可见成像光谱仪波长定标装置。该系统主要由具有高稳定性的300W氙灯系统、前置施瓦兹型聚光镜、高光谱分辨力的中阶梯光栅单色仪以及后置光学系统组成。利用ZEMAX光学设计软件,对该中阶梯光栅单色仪光学系统进行了优化设计。对设计结果进行了分析,设计结果表明,所设计的高分辨率紫外-可见成像光谱仪波长定标装置满足设计指标要求,扫描光谱范围270～500nm,光谱分辨力小于0.05nm,波长精度小于0.05nm。Referring to limitation of the conventional spectral calibration in Ultraviolet-Visible（UV-VIS） wave band,a high spectral resolution calibration device was built for ultraviolet-visible spectrometer.It primarily consists of a stable 300 W xenon lamp,a Schwartzschild mirror,an echelle grating monochromator,and a collimator.The optical system of the monochromator was optimized by using ZEMAX optical design software.The apparatus design is described and analyzed,and results show that it satisfies the design requirements of the monochromator.Spectral region from 270 nm to 500 nm can be scanned,and its spectral resolution is less than 0.05 nm with wavelength accuracy less than 0.05 nm.
