摘要：
A method of designing a flat-field planar concave grating for a miniature spectrometer is studied based on the second-order aberration theory. Because of flat-field imaging, the dominating aberration is defocusing. To obtain low defocusing, two steps are applied: first tune the detecting plane, then adjust the groove distribution.
