摘要： PROBLEM TO BE SOLVED: To provide an optical element with which desired optical pickup characteristics can be obtained even when the light of different wavelengths utilizes the common diffraction region of the optical element, a lens, and an optical pickup. SOLUTION: The objective lens 3 of the optical head device is bisected to an inner peripheral side refractive surface region 33 of a circular shape inclusive of an optical axis L and an outer peripheral side refractive surface region 34 annularly enclosing the outer periphery of the inner peripheral side refractive surface region 33 to a concentric form around the optical axis L. An inner peripheral diffraction grating 35 is formed by fine blazes 30 of a concentric form. Both of the first laser beam for a DVD and the second laser beam for a CD are diffracted by the inner peripheral diffraction grating 35. The aberrations when the blazes are actually worked are decreased by previously anticipating the occurrence of prescribed aberrations in an optical path function at the time of performing optical design of the objective lens 3.

摘要： PROBLEM TO BE SOLVED: To provide a measuring apparatus in which the quantity of irradiation light is made large when an object to be inspected is irradiated with light while effectively utilizing the irradiation light emitted from a light source, and by which the inclination of the object to be inspected can be measured with high resolution. SOLUTION: This measuring apparatus for the inclination of an object to be inspected is provided with a light source 11, a light receiving element 21, and a collimating lens 18 which changes light emitted from the light source 11 into parallel light so as to be cast on the object 19 to be inspected, and by which its reflected light is condensed so as to be image-formed by the light receiving element 21. The inclination of the object 19 to be inspected is measured on the basis of the image-formation position of the light receiving element 21. A condensing lens 12 is arranged and installed in an optical path between the light source 11 and the collimating lens 18. The arrangement and installation position of the collimating lens 18 is set at the rear of the optical path of a focal position which is condensed by the condensing lens 12. As a result, the object 19 to be inspected is irradiated with good efficiency with radiant light condensed by the condensing lens 12 through the collimating lens 18, and the image recognition accuracy of a formed image is enhanced.

摘要： PROBLEM TO BE SOLVED: To propose a lens unit which can be removed of chromatic aberrations, without expanding the dimensions in an optical axis direction.
SOLUTION: A first diffraction grating A, which removes the axial chromatic aberrations, is formed on an incident surface existing on the side of a diaphragm 50 of a third lens 30 of a small effective diameter among the lenses 10 to 40 constituting a zoom lens unit 100 and a second diffraction grating B, which removes the abaxial chromatic aberrations, is formed on an exit surface of the first lens 10 of a large effective diameter. Since the blaze shapes of the first and second diffraction gratings A and B are ≤2 μm in level difference and ≥10 μm in grating pitch, metal mold manufacturing and resin molding can be performed efficiently. In addition, assurance of high dimensional accuracy can be made as well.

摘要： PROBLEM TO BE SOLVED: To measure the inclination of a subject by means of an inexpensive and simple arrangement without using an expensive beam splitter and to reduce light power losses and prevent interference. SOLUTION: This apparatus for measuring the inclination of a subject includes a light source 11, a light-receiving element 19, and a collimator lens 17 for converting light rays emitted from the light source 11 into parallel rays to irradiate the subject 18 therewith and for collecting and focusing the reflected light rays onto the light-receiving element 19, and measures the inclination of the subject 18 from the imaging position of the light-receiving element 19. The above members are arranged so that when the subject 18 is not inclined, the optical axis (a) of the light rays incident on the subject 18 and the optical axis b of the light rays reflected from the subject 18 constitute a V-shape.
