? 2022 Elsevier LtdA focusing polycapillary was incorporated in the M?ssbauer spectrometer to achieve M?ssbauer spectrum from the point with the diameter of 150μm. Since such an apparatus is rather unique and so far it has not been described, a detailed views into the problematics of using the focusing polycapillary with 57Co source, and into the problematics of the scanning transmission M?ssbauer microscope alignment procedure are presented. This article presents the properties of the focusing polycapillary and its performance for 57Fe 14.4keV M?ssbauer radiation using 57Co radioactive source. The performance of the polycapillary is demonstrated with the measurement of the stainless steel. The obtained spectrum exhibited a similar signal to noise ratio as the M?ssbauer spectrum acquired by using a pinhole with the diameter of 200μm. The usage of the polycapillary optics could be a promising way in M?ssbauer spectroscopy, e.g. for measurements of tiny samples in an anvil cell.
