Abstract

SUMMARY The authors measure the optical properties of an objective lens for a telescope, signed «Domenico Selva» and recently discovered in the teaching laboratories of the Department of Physical Sciences of the University of Naples. They determine the composition of the glass by means of the technique of X-ray fluorescence. The lens was probably made during the first half of the eighteenth century by Domenico Selva or by his son Lorenzo.
