Abstract: A linear axis spectral analysis system is enclosed. The spectral analysis system utilizes a prism-volume holographic transmission grating-prism combination to achieve a linear axis between input and detector. This design, when held with low thermal expansion materials, is extremely insensitive to temperature and vibration, allowing for enhanced accuracy without the need of temperature control. Further, the spectral analysis system provides the ability for extreme compactness.

Abstract: The automatic chemical analyzer includes a turntable adapted to hold a plurality of disposable cuvettes. An optical system adjacent to the turntable can perform analytical absorbance or fluorescence tests on the contents of each cuvette as they are rotated on the turntable. A sample/reagent tray is rotatably mounted about an axis parallel to the turntable axis. A common probe arm pivoted about a third parallel axis mounts a pipette that can be moved along an arcuate path intersecting a cuvette access station on the turntable and at least one container access station on the sample/reagent tray for transferring liquids as required by specific test procedures. A sample tube entry port is provided to support individual draw tubes that are manually delivered to the analyzer at a sample access station and to facilitate removal of samples by the pipette without exposing operating personnel to accidental contact with liquid materials in the draw tube.

Abstract: An improved flat field grating spectrometer for increasing the spectral resolutiion and usable spectral range. The spectrometer comprises an entrance slit or port, a concave grating, a field flattening lens and detection means encompassing the desired spectral region and capable of providing separate measurements between different regions of the spectral image plane. A second embodiment provides a beam splitter (dichroic or neutral density) placed between the grating and the detector to divert a portion of the energy at selected wavelengths through a second field flattening lens to a second detection means.

Abstract: An optical system for a multidetector array spectrophotometer which includes multiple light sources for emitting light of selected wavelength ranges and means for selectively transmitting the selected wavelength ranges of light to respective slits of a multi-slit spectrograph for multiple wavelength range detection. The spectrograph has two or more slits which direct the selected wavelength ranges of the light spectra to fall upon a dispersive and focusing system which collects light from each slit, disperses the light by wavelength and refocuses the light at the positions of a single set of detectors.

Abstract: A method of making a corrected plane holographic grating within one band of wavelengths, intended for use in a diffraction apparatus in which light emitted by an entry source (1) is collimated by a spherical mirror (2) to the grating (4), which reflects parallel pencils to another spherical mirror (7), a focusing mirror, is disclosed. An auxiliary holographic grating (25) is created by the interference on a spherical surface (15) of a parallel pencil of light produced by the spherical mirror (7) subsequent to reflection onto a plane mirror (12) and of a divergent pencil deriving from the center of the surface (15). The auxiliary grating, corrected by the interference on a plane surface (22) of a parallel pencil produced by the spherical mirror (2) and of another parallel pencil produced by the auxiliary grating (25) illuminated from the center of the spherical surface, is then recorded.

Abstract: An optical cell provides a measuring chamber which is L-shaped with an absorbance optical path lying along the horizontal leg of the L. A second optical path is provided transverse to the absorbance path and sized to permit the passage of radiation into the entire L-shaped chamber. The exit slit for the cell receives radiation from the entire vertical leg of the L and may serve as the entrance slit to a photometer.

Abstract: The disclosure relates to dispersive lenses and spectrometers for performing a method of focusing holograms in which the hologram that is placed on a spherical surface plays an active part in the focusing. Contrary to focusing methods of the prior art wherein the focusing locus is determined as a function of the tangential object and image focal lines, the described invention determines the focusing locus as a function of the sagittal object and image focal lines. A stigmatic mounting (i.e. a perfect mounting to eliminate odd order abberations) results in the tangential and sagittal focal lines being identical. The description sets forth equations to cover all points in the focusing plane by suitable action of the phase variations generated by the hologram. The diffraction grating used is reflective and includes a fixed entrance slit and at least one fixed exit slit.

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.
