Abstract
A low-cost, broadband, astigmatism-corrected Czerny–Turner arrangement with a fixed plane grating is proposed. A wedge cylindrical lens is used to correct astigmatism over a broadband spectral range. The principle and method of astigmatism correction are described in detail. We compare the performance of this modified Czerny–Turner arrangement with that of the traditional Czerny–Turner arrangement by using a practical Czerny–Turner imaging spectrometer example.
