利用球面变线距光栅的平场像聚焦特性，设计了掠入射光谱仪。应用遗传算法对机械刻划光栅参数进行了优化选择。设计了2-5-nm和5-20-nm两种光谱范围的光栅，并分析了它们的制作公差。(C)1999年美国光学学会。
A grazing-incidence spectrograph is designed by use of the flat-field image-focusing property of a spherical varied-line-space grating. Optimum grating parameters for mechanical ruling are selected by application of genetic algorithms. Two gratings, one for 2-5-nm and the other for 5-20-nm spectral regions, are designed, and their fabrication tolerances are analyzed. (C) 1999 Optical Society of America.
