Patent ID: 8081554

Claim:
An optical pickup device comprising: a light source for emitting light in a first wavelength range; an optical element for transmitting the light emitted from the light source and guiding the emitted light to an optical disc, and for transmitting light reflected from the optical disc and guiding the reflected light to a detector unit; a supporting member for supporting the optical element through an adhesive; a first light blocking member for blocking the light emitted from the light source from entering the adhesive when the optical element guides the emitted light to the optical disc; and a second light blocking member for blocking the light reflected from the optical disc from entering the adhesive when the optical element guides the reflected light to the detector unit, wherein at least one of the first light blocking member and the second light blocking member is made of a material that blocks the light in the first wavelength range and transmits light in a second wavelength range, wherein the first wavelength range falls in the range from 398 nm to 420 nm, and the second wavelength range falls in the range from 350 nm to 380 nm.
