Abstract

Bandwidth is an important specification for monochromator and spectrograph. It varies with different slit widths and wavelengths. In actual spectral measurement, it is usually need to know the bandwidth. In the case of a Czerny-Turner double monochromator, we measured its bandwidth in finite different wavelengths as well as slit widths. Bandwidth can be represented as a function of wavelength and slit width. After the experiment, we get bandwidth in some discrete wavelengths and slit widths, bandwidth in other wavelength and slit width can be computed through mathematical process of the data that already acquired.
