Aberration-corrected Czerny-Turner imaging spectrometer with a wide spectral region.
A modified asymmetrical Czerny-Turner arrangement with a fixed plane grating is proposed to correct aberrations over a wide spectral region by analysis of the dependence of aberration correction for different wavelengths. The principle and method of aberration correction are described in detail. We compare the performance of this modified Czerny-Turner arrangement with that of the existing Czerny-Turner arrangement by using a practical Czerny-Turner imaging spectrometer example.
