Abstract: A microprocessor based spectrophotometer including manual keyboard command for sequencing a monochromatic energy beam through a spectral range of wave-lengths to a keyboard selected wavelength. A manual adjustment knob is thereafter rotatable for generating a 4-bit gray code signal which successively changes as the adjustment knob is rotated. The microcomputer senses a change in the gray code signal and indexes (steps) the wavelength of the monochromatic beam in proportion to the positional change of the adjustment knob as indicated by the changing gray code. A visual display indicating wavelength setting and spectral response, is updated conjointly with manual wavelength adjustment.

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: A scanning spectrophotometer employes fixed optics to produce a dispersionf optical energy. The dispersed optical energy is scanned by a fixed position surface acoustic wave photoelectric transducer.

Abstract: The spectral lines associated with a sample of material under examination are deflected from their normal optical path by an angle which varies logarithmically with time toward a sheet of photographic film. The film is thereby exposed to provide a photographic image of the spectral lines which taper in intensity toward nonexposure, and the length of the line or lines is thus representative of the concentration of an element present in the sample under examination.
