    Abstract: PROBLEM TO BE SOLVED: To provide an optical method and an optical apparatus for displacement of particles (P). SOLUTION: The optical apparatus for displacement of the particles (P) is provided with both a substrate (6) in which at least one strip (5) made of at least one thin film is accumulated and the strip (5) having an optical thickness gradient along its axis line so that the displacement of the particles (P) may occur along the axis line of the strip (5) when electromagnetic waves (L) inadiate the apparatus. This invention may be applied to the classification and/or analysis of the particles. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To obtain high absorptivity in the visible ray to near infrared ray region while minimizing the risk of a mechanically unstable state by forming a metal thin film in such a manner that the refractive index of the thin film is larger than the refractive index of the same metal in a bulk state and that the absorption const. of the film is smaller than the absorption const. of the metal in a bulk state in a specified spectral range. SOLUTION: The coating part consists of a thick metal layer 4 of a film thickness in several tens nm order, an alumina layer 6 of thickness in 20 to 30 nm order, an optically discontinuous thin aluminum absorbing layer 8 having

    Abstract: PROBLEM TO BE SOLVED: To prevent transmission of light over the critical wavelength in the UV region and to avoid reflectance of light equal to or lower than the critical wavelength by forming a dielectric laminated body which has an antireflecting function in the UV region and forming a metal base which acts as a preventing function in other region of the spectrum. SOLUTION: A dielectric structure 14 comprising plural films is directly formed on a metal film 12. The dielectric laminated body 14 has an antireflecting function against light of wavelength λsatisfying λ

    IPC: G11B7/257

    Abstract: The invention relates to optical information storage. According to the invention, what is provided is a high-resolution optical information storage structure, comprising a substrate (10) provided with physical marks, the geometric configuration of which defines the information recorded, a superposition of three layers over the top of the marks on the substrate, and a transparent protective layer over the top of this superposition, the superposition comprising an indium antimonide or gallium antimonide layer (14) inserted between two ZnS/SiO2 dielectric layers (12, 16). The information may be prerecorded in the substrate with a resolution (in terms of size and space) better than the theoretical read resolution permitted by the wavelength of the read laser. The non-linearity in behaviour of the three-layer superposition allows the information to be read if the laser power is well chosen.

    Abstract: The invention relates to an analytical support for determining an analyte such as a DNA or RNA target, by carrying out a specific reaction of binding (hybridization) of said analyte with a ligand specific for this analyte, and determining the binding reaction by means of at least two fluorescent labels present on the analyte. This determination is carried out by applying an excitatory field and detecting the fluorescent emission of the various fluorescent labels. According to the invention, the support comprises a substrate coated with one or more layers of material(s) forming an assembly capable of decreasing or increasing the excitatory field for at least one of the fluorescent labels compared to the others. The ligands are attached to the final layer of the assembly. A layer of SiO 2 on a substrate of silicon can be used with the fluorescent labels Cy3 and Cy5.

    Abstract: The measuring apparatus contains first (207) and second (209) light reflectors which have at least two mirrors or a matrix of mirrors (208) integrated in a single support, and the first and second reflectors form a system of resonant cavities. A support (200) such as a biochip with a number of biological samples (204) is placed between the first and second reflectors. At least one light pulse with a time span of between 100 picoseconds and 100 nanoseconds is emitted in the resonant cavities, and the responding light signals from the cavities are measured with the aid of one or more photodiodes, enabling the light absorption of the samples, containing DNA or RNA marked by fluorophores, to be determined.
