Abstract

Analytical relations among finesses of an Axicon - scanned Fabry - Perot spectrometer are derived. The composition of instrumental profile is discussed and the criterion for an approximation of the step function by a Gaussian one is introduced. In this way numerical computation for each particular case can be avoided and for deconvolution of scanned profile one may use the standard procedure for Voigt profile. An analytical expression for the broadening of the instrumental profile due to the axicon is derived. Experimentally it is shown that the axicon behaves as a linear scanning element.
