Scientific paper

A determination is made of the optical luminosity function (OPLF) of an infrared flux-limited sample of IRAS galaxies. The sample includes 92 objects; among these are an infrared-loud quasar and two previously known Seyferts. The OPLF of the IRAS galaxies in the sample shows that in the magnitude range between -22 and 18, IRAS galaxies represent about 15 percent of field galaxies. At low luminosities, Mj greater than -19 mag, there may be a deficiency of IRAS galaxies relative to the field galaxies. The far-IR luminosity function of the sample is also derived; it agrees well with other determinations.
