    Abstract: A spectrometer or multiple wavelength absorbance detection method and apparatus providing improved accuracy for an array of measurements at different wavelengths. The spectrometer utilizes a multiple wavelength illumination system with an array of independent detectors with different pathlength cells, where each cell is illuminated with predominately monochromatic light after separation by a light dispersing element. Each sample cell has an optical pathlength, optics and photodetection device that are optimized for its particular wavelength to accurately measure absorbance through an expected substance.

    Abstract: A 1:1 Offner mirror system for imaging off-axis objects is modified by replacing a concave spherical primary mirror that is concentric with a convex secondary mirror with two concave spherical mirrors M1 and M2 of the same or different radii positioned with their respective distances d1 and d2 from a concentric convex spherical diffraction grating having its grooves parallel to the entrance slit of the spectrometer which replaces the convex secondary mirror. By adjusting their distances d1 and d2 and their respective angles of reflection .alpha. and .beta., defined as the respective angles between their incident and reflected rays, all aberrations are corrected without the need to increase the spectrometer size for a given entrance slit size to reduce astigmatism, thus allowing the imaging spectrometer volume to be less for a given application than would be possible with conventional imaging spectrometers and still give excellent spatial and spectral imaging of the slit image spectra over the focal plane.

    Abstract: An active monolithic optical device for wavelength division multiplexing (WDM) incorporating diode laser arrays, an output coupling waveguide and a curved Rowland circle based grating to produce a plurality of individual laser beams at slightly different wavelengths is integrated in a common electro-optic material. The wavelength of each laser source is determined by the geometry of the array and the diffraction grating design. The output of all the channels can be collected into a concentrator or lens to be multiplexed in a single output. Applications include a WDM optical amplifier and WDM laser source.

    Abstract: An improved method and apparatus for focused stigmatic imaging with spherical concave diffraction gratings incorporates a concave spherical diffraction grating with parallel, normally ruled lines. An entrance light beam source or projector propagates a beam of light to be analyzed through an entrance point and onto the surface of the diffraction grating. A light detector or analyzer is positioned at or near a detection point for detecting or characterizing the light diffracted from the grating. The entrance point and detection point are positioned in spaced-apart relation to each other and to the grating according to disclosed formulae, such that they are in respectively corresponding stigmatic or near stigmatic focus with each other.

    Abstract: An improvement in the measuring elements of closed circuit systems for controlling-correcting printing in offset printing machines is provided. The values of measurements are amplified, analogically commutated, converted from analog to digital form, and then microprocessed so as to be compared with standard values established in a memory program provided for each one of the valves controlling the printers block of each one of the printing bodies. A reading is taken decomposed into three variables, each one of which corresponds to one of the three basic colors of the visible spectrum in which the light from the colored stain is diffracted by means of a ROWLAND diffraction grating in which there is reflected the light from optical fibers arranged at 45.degree. angles with respect to the printing paper, and which direct a beam of light on the colored stain. At the point of convergence of each one of the diffracted colors, there is arranged a photo pickup device whose signal is amplified by a logarithmic amplifier and connnected to a digital signal which is sent to a microprocessor for processing.
