Abstract: PROBLEM TO BE SOLVED: To permit shortening of a length of an image pickup device including a lens and an image pickup element and further permit reduction of a positional error between the lens and image pickup element. SOLUTION: A refractive index distribution lens 1 having a single refractive index having a refractive index distribution nearly proportional to a square of a distance from an optical axis 2 in a sectional plane perpendicular to the optical axis 2 is provided as an imaging lens in the vicinity of an image pickup plane 5 of an image pickup element 4. More specifically, a positional relationship between the image pickup element and lens is fixed with an adhesive such as, e.g. organic solvent 4. And an infrared ray cutting filter 6 is formed in a light incident plane of the lens 1.

Abstract: PROBLEM TO BE SOLVED: To reproduce correctly even optical disks with different thickness of substrates by making pass through one side component between normal light or abnormal light related to an optical axis of a polarizing hologram element between separated light beams. SOLUTION: A collimate lens 15 converts the light beam transmitting through a beam splitter and facing to the optical disk D to the parallel light beams. The polarizing hologram element 16 is constituted so that a concentric grating is formed on a surface of a lithium niobate substrate 16a by a proton exchange method, and a dielectric film is formed on the grating, and prescribed polarization characteristic and lens characteristic are given. The element 16 acts so that e.g. a normal light component between the light beam 16d entering from a semiconductor laser element 11, transmitting through the beam splitter 12 and incident on the element 16 is transmitted through, and an abnormal light component is diffracted and converged related to the optical axis 16c.

Abstract: PURPOSE: To provide an optical pickup miniaturized in constitution with the cost reduced. CONSTITUTION: This optical element consists of a 1st diffraction element 30 for splitting incident light of linear polarization into 1st and 2nd components which are orthogonal to each other and a 2nd diffraction element 31 for splitting the light into 3rd and 4th components which are nearly transmitted through 1st order diffracted light of the 1st component emitted from the 1st diffraction element and are also orthogonal to 0-th order diffracted light of the 2nd component emitted from the 1st diffraction element. Then, the 1st diffraction element and the 2nd diffraction element constitute the optical element 25, so as to be polarization holograms disposed on both opposite sides of a substrate 30a of a hologram element respectively.
