The Evaluation of Spectral Resolution in the Optical Design of a Czerny-Turner Spectrometer

In this study, we propose a method of evaluating the spectral resolution crossed-asymmetric Czerny-Turner spectrometers by comparing impact different slit functions on optical transfer function, and widths, through simulation experiments. The results show that, Gaussian function is suitable for narrower such as 25 ?m, rectangle or convolution slit-scattering with wider 50 150 200 ?m. proposed can provide guidance in evaluation preliminary design process spectrometers.
