Abstract: We present a catalog of secondary photometric standard stars in the neighborhood of 14 gravitationally lensed quasars. These stars were verified to be non variable using long-term monitoring. The instrumental magnitudes of the new standard stars have been transformed to the Johnson-Cousins BV(RI)c photometric system. For ten gravitational lenses (GLs) we also provide the BV(RI)c mean magnitudes of the integrated flux of all the lens components, for the epochs of the photometric calibration. Based on observations made with a) the 1.0 m telescope at Wise Observatory, Israel, b) the 1.3 m telescope at Skinakas Observatory, Crete, Greece, and c) the 1.9 m SAAO telescope, Sutherland Observatory, South Africa. Tables \ref{info}-\ref{colors-gls} and Fig. \ref{findingchart} are only available in electronic form at http://www.edpsciences.org
