    摘要: Disclosed herein is a sensor utilizing attenuated total reflection. The sensor includes a first dielectric block; a thin film layer, formed on a first face of the dielectric block, for placing a sample thereon; and a light source for emitting a light beam. The sensor further includes an optical incidence system for collimating the light beam, and making the collimated light beam enter the dielectric block at a predetermined incidence angle so that a condition for total internal reflection is satisfied at an interface between the dielectric block and the thin film layer; a photodetector for detecting the refractive index distribution of the sample obtained within a plane along the interface, by detecting an image carried by the light beam totally reflected at the interface; and an optical compensation system for compensating for image distortion produced by the dielectric block when the predetermined incidence angle of the light beam varies.

    摘要: A measuring apparatus for measuring the state of attenuated total reflection over time for a single measuring unit without being affected by the change in measuring conditions arising from replacement and resetting of the sample. A light beam is entered into the interface between a dielectric block and a metal film having a dielectric film thereon at various incident angles within the angle range that creates two or more dark lines due to attenuated total reflections, and the variation in the positions of other dark lines are measured with reference to the dark line having the least positional variation among them.

    摘要: A sample analyzer includes a light source for emitting light for analyzing a sample and a probe having at its one end a light outlet aperture which is smaller in diameter than the wavelength of the light emitted from the light source. An incident optical system causes the light emitted from the light source to enter the probe through the other end of the probe. A sample support supports the sample in a position where the sample is exposed to near field light emitted from the light outlet aperture of the probe. A diffusion panel receives scattered light generated by interaction between the surface of the sample and the near field light and visualizes the intensity distribution pattern of the scattered light. A CCD image taking device takes an image of the intensity distribution pattern of the scattered light visualized by the diffusion panel, and the image of the intensity distribution pattern of the scattered light taken by the image taking device is displayed on a CRT.

    摘要: A surface plasmon sensor comprises a prism, a metal film, which is formed on one surface of the prism and is brought into contact with a sample, and a light source for producing a light beam. An optical system causes the light beam to pass through the prism and to impinge upon an interface between the prism and the metal film such that various different angles of incidence may be obtained with respect to the interface. A photodetector detects an intensity of the light beam, which has been totally reflected from the interface, with respect to each of the various different angles of incidence. An electrode stands facing the metal film with a liquid sample intervening therebetween, and a DC voltage is applied across the electrode and the metal film. A substance contained in the liquid sample is thus analyzed quickly and with a high sensitivity.

The light scattering layer has a first scattering portion having an uneven structure and a lower refractive index than the light emitting layer, and second scattering portions that fill at least the bottoms of recesses of the uneven structure and has a different refractive index from the first scattering portion. The distance between the bottoms of the recesses and the surface of the light transmitting electrode is a seepage depth of the evanescent light or less.
