  • The first-order astigmatism-free conditions in a crossed Czerny-Turner (C-T) structure spectrometer are derived in this paper and the optical parameters determined for a relative aperture of 1: 8 and a working range of 780 nm to 1 014 nm. An astigmatism-free crossed C-T spectrometer is built up with ZEMAX software, and a corresponding coma-free crossed C-T spectrometer is also built up for the comparison. The initial structures for the two types of crossed C-T optical systems are then optimized, and the performance merits are compared. It is shown that the astigmatism-free crossed C-T structure has superior optical performance with an RMS for the spot diagram only 12% to 52%, compared with that of the corresponding coma-free C-T structure over the working range. This indicates that the astigmatism-free crossed C-T structure possesses not only a better energy concentration along the slit direction, which is beneficial to spectrometers requiring larger condenser capacity, but also a smaller spot diameter along the direction perpendicular to the slit indicating that a higher spectrum resolution is achievable.
