With the advantages of quick identification, simple operation, reliable working, no pollution, non-invasive detection, the Czerny-Turner structure micro spectrometer as an important analysis tool has a wide range applications. In this paper, the domestic and foreign products of the current micro spectrometers are introduced, at the same time, the performance parameters are summarized and ... [Show full abstract] compared. The optical aberrations including spherical aberration, coma, astigmatism and field curvature are further summarized and discussed. The development direction and prospects of the Czerny-Turner structure micro spectrometer are prospected. The revelant outline can provide the basis for the development of the micro CT structure spectrometer with a wide band, low cost and high performance index.
