An optical scanning device for scanning an optical record carrier includes a radiation source and a beam splitter arranged to pass a first portion of the source beam to the record carrier, and a second portion to an intensity sensor. A signal detector is arranged in the path of the beam reflected by the record carrier. False radiation reflected by the signal detector can be prevented from reaching the intensity sensor by tilting the signal detector. A polarization filter may be arranged in front of the intensity sensor to prevent false radiation reflected by the radiation source and by the signal detector from reaching the intensity sensor.
