Patent ID: 7099254

Claim:
An optical scanning device for scanning an optical record carrier, said device including a radiation source for emitting an incident radiation beam, a beam splitter located in the path of the incident radiation beam from the radiation source to the location of said optical record carrier and arranged to pass a first portion of the incident beam intensity, which is incident upon the beam splitter, towards the optical record carrier and to pass a second portion of said incident beam intensity towards an intensity sensor for sensing radiation of the incident beam, and a radiation-sensitive signal detector for converting a radiation beam reflected from said optical record carrier and passing along a path including the beam splitter into electric detector signals, characterized by means for redirecting reflected radiation reflected from the radiation-sensitive signal detector and/or the radiation source from reaching the intensity sensor, said means for redirecting including a wedge-shaped element arranged in the path through the beam splitter up to the signal detector.
