A lens specifying apparatus comprising a light source (21) for projecting a measuring light beam on a lens (30) under examination, an area CCD (35) image receiving element for receiving the measuring light beam transmitted by the lens (30) under examination, a filter disc (64) disposed, as means for providing spectral transmittances, at a midpoint of an optical path extending from the light source (21) to the area CCD (35), and a processing circuit (37) for calculating the refractive characteristics and spectral transmittances of the lens (30) under examination on the basis of an output of the area CCD (35) and displaying the refractive characteristics and spectral transmittances on a monitor (3).
