摘要： An optical pickup which is compatible with different types of media is disclosed. A plurality of light sources emit light with different wavelengths. Light path changers change the path of light emitted by the plurality of light sources so that the light is incident upon an objective lens. The objective lens focuses the incident light onto a recording medium. A collimating lens is disposed in front of the objective lens to collimate the incident lights. The collimating lens is movable to correct a spherical aberration. A diffractive optical element is disposed in a path of a light with a short wavelength and has a diffractive surface to correct a chromatic aberration.

摘要： An optical lens system of a mobile camera is provided. The lens optical system includes: an optical lens in which bilaterally symmetrical off-axis lens systems corresponding to the divided view angles are integrally formed and arranged in parallel on the same plane, the optical beams incident at the divided view angles being transmitted through the respective off-axis lens systems; and an image sensor for receiving the optical beams transmitted through the off-axis lens systems, the image sensor being bisected into a green light receiving region and a mixed light receiving region of red and blue colors. Accordingly, the mega resolution can be achieved using the optical lens having the height of VGA grade. Moreover, as the whole length of the optical lens system in the mega optical system is greatly reduced, the camera optical system can have the slim profile.
