  • Optical scanning device
    Patent number: 7050364
    Abstract: An optical pickup unit for scanning an optical disk includes a first optical branch including a first radiation source for emitting a first radiation beam of a first wavelength, and a dichroic mirror (8) located in the path of the first radiation beam for reflecting the first beam towards the disk, and a second optical branch including a second radiation source for emitting a second radiation beam of a second wavelength, different to said first wavelength, and a folding mirror (28) located in the path of the second radiation beam for reflecting the second beam towards the disk. The first and second branches are stacked in the axial direction of the disk, and are arranged substantially perpendicularly when viewed along the axial direction.
