We present an Atlas of high resolution (resolving power tex2html_wrap_inline979) synthetic spectra based on the 1993 release of atmosphere models and codes by Kurucz. The spectra are given in the wavelength interval 4850-5400Å  for eleven values of effective temperature in the range 4000-8000K, for nine surface gravities in the interval 1.0-5.0dex, and for seven metallicities spanning from -1.0 to +0.5dex. The Atlas is aimed mainly at the analysis of composite stellar populations by means of suitable spectral features extracted from the spectra and identifiable in the observed composite light of clusters and galaxies. The high resolution used in the computations makes the Atlas also suitable for chemical abundance analyses.
