JF - Microscopy and microanalysis N2 - Four years ago BAM has made available via its webshop a test material, EDS-TM001, as well as an accompanying software package, "EDX spectrometer check", to be employed by both EDS (energy dispersive spectrometer) users and manufacturers to check and pecify, respectively, the performance of an EDS.

A routine procedure for the characterisation of a polycapillary X-ray semi-lens with a scanning electron microscope (SEM) having attached an energy dispersive spectrometer (EDS) is presented in this paper. A key issue of the procedure consists of fitting the semi-lens in front of the EDS for spectra acquisition. Relevant semi-lens parameters such as focal distance, full width at half maximum (FWHM) of the acceptance area, and transmission are determined in parallelising mode of the semi-lens. Special attention has been paid to the calculation of the transmission.
