    Abstract: A new immunoassay system is provided for the detection of ligands or ligand binding partners in solution in a heterogeneous format. The invention relies upon the detection of back scattered light from an evanescent wave disturbed by the presence of a colloidal gold label brought to the interface by an immunological reaction. The evanescent wave existing at the interface in turn is the result of a totally internally reflected incident light wave. Placement of the detector at a back angle above the critical angle insures a superior signal-to-noise ratio. Apparatus and methods for scanning, detecting and manipulating light including a scattered total internal reflectance immunoassay system are provided.

    Abstract: A confocal measuring microscope including a spectrometer and autofocus system sharing common optical elements in which the intensity of light entering the spectrometer from a particular spot on a workpiece is used to determine a focus condition for the same spot. The microscope includes at least one light source, an illumination field stop, and a microscope objective that images the stop onto a workpiece supported by a movable platform. The objective also forms an image of the illuminated portion of the object. An aperture in a second stop and intersecting the image plane passes light from part of the image to the spectrometer, while viewing optics are used to view the image. In one embodiment, a detector is placed at the zero order position, while in another embodiment a laser is placed at the zero order position. In the later embodiment an integrator circuit connected to the detector array replaces the zero order detector for measuring the total intensity of light entering the spectrometer. A best focus condition occurs when the total intensity is a maximum for a positive confocal configuration, i.e. where source and detector are on opposite sides of their respective field stops from said workpiece, and a minimum for a negative confocal configuration, i.e. where the source and workpiece are on the same side of a reflective illumination field stop with aperture. The movable platform may be scanned axially to achieve and maintain object focus as the object is scanned transversely.

    Abstract: A wavelength discriminator designed to collect broadband, multiple wavelength input energy, to isolate specific narrow bands of interest, and to image such narrow bands of interest upon closely spaced, separate detectors. This discriminator comprises optical devices (22, 18) for directing incoming radiant energy of a certain quality and involving a wide range of wavelengths through first (26a) and second (26b) wavelength selective reflectors separated by a medium that transmits the wavelengths of interest. The wavelength selective reflectors in accordance with this invention are in a non-parallel configuration and disposed in a double pass geometrical arrangement wherein energy of a certain wavelength reflected from the second wavelength selective reflector (26b) passes back through the first wavelength selective reflector (26a), with the energy from the first and second wavelength reflectors thereafter being directed onto respective detectors (32aand 32b). An embodiment involving a third wavelength selective reflector (26c) grouped with the first and second reflectors may be utilized, wherein energy of a different wavelength reflected from the third wavelength selective reflector passes back through both the second and first wavelength selective reflectors, with the selected wavelengths thereafter falling upon three separate detectors (32a, 32band 32c) of the array.

    Abstract: To provide a confocal displacement sensor that can prevent deterioration in measurement accuracy due to a spherical aberration of an optical member. The confocal displacement sensor includes a light source for light projection configured to generate light having a plurality of wavelengths, a pinhole configured to emit detection light by allowing the light emitted from the light source for light projection to pass, an optical member configured to generate an axial chromatic aberration in the detection light emitted via the pinhole and converge the detection light toward the measurement object, a measurement control section configured to calculate displacement of the measurement object on the basis of, in the detection light irradiated on the measurement object via the optical member, detection light passed through the pinhole by being reflected while focusing on the measurement object, and a head housing configured to house the pinhole and the optical member. The optical member includes a first diffraction lens configured to diffract the detection light and a first refraction lens configured to refract the detection light. The first refraction lens is disposed with a non-diffraction surface exposed from the head housing.

    Abstract: A light radiating portion (11a, 11b, 12, 51, 52) radiates light with wavelength λ1 having predetermined absorptivity for an object (16) and light with wavelength λ2 having smaller absorptivity for the object (16) than the wavelength λ1, to a target, so as to scan in 2-dimensional directions. A light receiving portion (17) receives scattered lights reflected by the target based on light with wavelength λ1 and light with wavelength λ2. A measuring portion (18) generates information used for detection of the object (16) at the target, based on difference between the two scattered lights with wavelength λ1 and wavelength λ2 received by the light receiving portion (17). An output portion (53) outputs whether or not the object is present at the target, by 2-dimensional area information, based on scanning by the light radiating portion (11a, 11b, 12, 51, 52) and information generated by the measuring portion (18).
