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: The disclosure is directed to a spectrophotometric measuring device equipped with a plurality of channels which automatically analyze many specimens with different testing items in a short period of time for application in biochemical automatic analysis or the like. The device of the invention is characterized in that white light from one light source is subjected to spectral diffraction through a long slit in X direction and wavelength dispersion irradiation light of an optical system including a spectroscope for dispersing spectrum of monochromatic light in Y direction intersecting at right angles with the slit, is projected onto one plate surface so as to select positions of the plate surface in the Y direction and X direction, and by providing the incident end faces of the optical fibers on the selected positions for free change-over, monochromatic lights of arbitrary wavelengths determined by the respective testing items are taken out, while the sample cell and detector are disposed to confront the optical fiber incident end faces for detection of intensity of light transmitting through the sample cell.

Abstract: Apparatus for emission spectrochemical analysis wherein the sample to be analyzed is excited by repeated spark discharge to emit light, which is dispersed to produce a spectrum containing emission lines characteristic of the elements in the sample. The intensity or quantity of light of each of the emission lines of the elements to be determined and that of the corresponding one of the emission lines selected as the internal standards for the elements to be determined are measured each time a spark discharge is produced to obtain the ratio of the former intensity or quantity to the latter at each spark discharge, and the ratios resulting from a predetermined number of spark discharges are averaged for each of the elements to be determined. From the average the content of each of the elements is read on a calibration curve.

Abstract: A scanner having an instantaneous narrow field of view determines spectral and positional information of a point source of optical radiation in a relatively wide field of view. A first optical path includes the scanning means, a dispersion means, and a first detector means so that different wavelengths of the source are convoluted to impinge on the first detector means at different times during a scan of the field of view. A second optical path includes the scanning means, the second detector means, and a narrow bandpass filter for enabling approximately monochromatic energy of the source to impinge on a second detector means displaced from the first detector means. Thereby, a predetermined wavelength is imaged on the second detector means at a time during a scan that differs from the time when that wavelength is imaged on the first detector means, even though the source angular position in the field of view is substantially the same for both of the optical paths. To enable the system to be responsive only to point sources, to the exclusion of nonpoint sources, each of the first and second detector means is divided into a multiplicity of separate, spaced detector elements. Each of the detector elements has a length in the direction of scan no greater than the length of the point source imaged on the first and second detector means. In response to the amplitude of energy impinging on the elements of the second detector means, a signal replica of the convoluted spectral energy impinging on one of the elements of the first detector means is coupled to a signal processing network that recognizes point sources having a predetermined spectral signature and enables the position of the recognized sources to be determined.

Abstract: An improved analyzer utilizes electron scanning techniques to examine the spectrum of radiant energy. A comparable spectrum of the background is provided, and the two are alternately scanned. The spectrum can also be ''''folded'''' into a plurality of vertically aligned segments with an adjacent area of corresponding background spectra, and a conventional t v raster scan can be employed. Appropriate processing circuits subtract the background from the signal and store the result. Stored quantities can represent the intensity of incident radiation at each wavelength.
