A new advanced optical design based on the Wadsworth mounting for a broadband stigmatic, coma-free practical spectrometer with high imaging quality is presented. By the addition of an inclined cylindrical lens with a wedge angle, the stigmatic imaging conditions in a broad waveband have been obtained by our analysis. An example which presents excellent optical performances over a spectral broadband of 380nm centered at 570nm has been designed to certify the analysis.
