    Abstract: Systems and methods for filter based spectrographic analysis are provided that permit rapid analysis of bioanalytes. Systems include devices for illuminating a sample with electromagnetic radiation and capturing radiation emitted from the sample. Emitted radiation can be collected by a plurality of waveguides each associated with a filter for a particular wavelength of radiation. Focusing devices are associated with filters and waveguides in certain embodiments. Radiation captured by waveguides can then be transmitted to a remote detector, which can determine the intensity of radiation for each waveguide. The use of a plurality of filters having different, band pass characteristics can permits the simultaneous detection of a plurality of different wavelengths of radiation emitted by a sample, thereby providing spectrographic information about the sample under study. Systems can include computers for storing acquired spectrographic information, addressable arrays of samples, and information security measures. Spectrographic information of samples can be diagnostic tools for identifying and quantifying a variety of different materials, including bioanalytes.

In another embodiment, the spectrometer is combined with a polychromatic imaging camera array disposed adjacent said entrance slit for recording said image.

    Abstract: An optical relay having a pair of simple lenses and an opaque barrier defining an aperture. In a spectrometer, the optical relay is positioned between a light source and an opaque barrier defining a slit to focus light of a reference wavelength w.sub.r onto the slit. The location of the aperture and the choice of w.sub.r are selected so that the flux of light through the slit is substantially flat as a function of wavelength.

    Abstract: An improved optical system is disclosed for rapid, accurate spectral analysis of the reflectivity or transmissivity of samples. A concave holographic diffraction grating oscillated at high speed is utilized to provide a rapid scanning of monochromatic light through a spectrum of wavelengths. The grating is positively driven at very high speed by a unique cam drive structure comprising identically shaped conjugate cams. The rapid scan by the grating enables the reduction of noise error by averaging over a large number of cycles. It also reduces the measurement time and thus prevents sample heating by excessive exposure to light energy. A filter wheel having dark segments for drift correction is rotated in the optical path and is synchronous with the grating. Source optics is employed to optimally shape the light source for particular applications. The system optics further includes a unique arrangement of lenses, including cylindrical lenses, to obtain the best light source shape which results in maximum light throughput. Fiber optics are also employed and arranged to meet the optimum requirements of the system for light collection and transmission through portions of the optical system.

    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.
