We have performed a comprehensive identification program of optically faint extragalactic IRAS sources by use of deep R band CCD images for 99 sources. We present positions and the morphological structure of the optical counterparts as well as coadded IRAS fluxes. Integral R band photometry is given for 67 IRAS sources and a total of 113 galaxies. Also B band photometric data are listed for 51 IRAS sources and 88 galaxies in total. Redshifts for 53 IRAS sources and a total of 87 individual galaxies are presented. More than 50 percent of the cases with a definite identification are galaxies with peculiar morphological structure. The individual components of the multiple systems for which we have measured redshifts show only small redshift differences, indicating that they are real physical systems.
