Inverse Convolution to Correction of Aberrations in Spectra Recorded with a Seya-Namioka Monochromator

Abstract

Inverse convolution has been used to remove the effect of aberrations in the spectra recorded with a Seya-Namioka monochromator. The factors which affect the variation of the slit function with wavelength scanning are discussed. To suppress the effect of these factors, a simple method of the determination of the inverse convolver is given. The experimental results indicated that the inverse convolution provides a simple and very effective means of correcting the aberrations of a Seya-Namioka monochromator.
