We have used an updated version of the empirically and semi-empirically calibrated Ba Se L library of synthetic stellar spectra of Lejeune et al. (1997, 1998) and Westera et al. (1999) to calculate synthetic photometry in the (UBV)$_J$(RI)$_C$ JHKLL$^\prime$M, HST-WFPC2, Geneva, and Washington systems for the entire set of non-rotating Geneva stellar evolution models covering masses from 0.4-0.8 to 120-150 M_ M$_{\odot}$ and metallicities $Z$=0.0004 (1/50 Z_ Z$_{\odot}$) to 0.1 (5 Z_ Z$_{\odot}$). The results are provided in a database[*]which includes all individual stellar tracks and the corresponding isochrones covering ages from 10$^3$ yr to 16-20 Gyr in time steps of $\Delta \log t=$ 0.05 dex. The database also includes a new grid of stellar tracks of very metal-poor stars ($Z$=0.0004) from 0.8 - 150 M_ M$_{\odot}$ calculated with the Geneva stellar evolution code.
