  • Patent number: 8027031
    Abstract: In a spectrographic workpiece metrology system having an optical viewing window, the viewing window is calibrated against a reference sample of a known absolute reflectance spectrum to produce a normalized reflectance spectrum of the reference sample, which is combined with the absolute reflectance spectrum to produce a correction factor. Successive production workpieces are measured through the window and calibrated against the viewing window reflectance, and transformed to absolute reflectance spectra using the same correction factor without having to re-load the reference sample.

  • Patent number: 8009277
    Abstract: A method for determining simultaneously from an oxidized black liquor sample an amount of sulfide, an amount of total dissolved solids, and an amount of effective alkali present in the sample, wherein the sulfide amount, the total dissolved solids amount, and the effective alkali amount are determined by subjecting the sample to attenuated total reflection (ATR) ultraviolet/visible (UV/V) spectroscopy over a wavelength of from about 190 to about 500 nm. Data from analyzing oxidized black liquor samples, and from analyzing one or more black liquor samples which may be subjected to black oxidation, may be used in a black liquor oxidation (BLOX) system for monitoring and/or controlling sulfur emissions from a kraft process.

  • Patent number: 8004661
    Abstract: A method, apparatus, and system for a sorting flow cytometer include an objective lens having an optical axis coaxially aligned with the flow path at the focal point. A controllable energy source selectively alters an analyte according to a determination of whether the analyte is in a desired sub-population. In various embodiments, one or both of the emission from the controllable energy source and/or the emission from an illumination energy source passes through the objective lens. In some embodiments in which the emission from the controllable energy source passes through the objective lens, the objective lens may focus the emission from the controllable energy source at a different point than the focal point of a signal detected from the analyte and, in particular, at a point closer to the objective lens.

  • Patent number: 7982873
    Abstract: A method and system are provided to correct differences among multiple spectrophotometers. In one form, one spectrophotometer of a plurality that may be present in an image rendering system is treated as “primary”. Additional spectrophotometers are treated as “secondary”. The spectrum of a color from a secondary spectrophotometer is transformed by a linear transformation to an adjusted spectrum, which then is converted to L*a*b* (if desired) using standard techniques. The L*a*b* thus produced is, on average, substantially closer to the L*a*b* that the primary spectrophotometer would have produced when measuring the same color than it is to the L*a*b* that the secondary spectrophotometer would have produced without any correction. The linear transformation is generated by linear regression to minimize the spectral error, followed by non-linear optimization to minimize the error relative to a color difference metric—such as DeltaE 2000.

  • Patent number: 7978325
    Abstract: A light amount is increased and an analyzing accuracy can be kept in accordance with an enlargement of a load angle, however, a scattered light tends to be loaded in an analysis accompanying the scattered light and a dynamic range of a concentration which can be measured becomes narrow. A light is dispersed by a light dispersing portion, a load angle of the received light is changed per wavelength, the load angle is made larger in the light of a wavelength having a small light amount, and the load angle is made smaller in the light a wavelength having a large light amount and used for an analysis accompanying a scattered light. Accordingly, it is possible to gain a dynamic range of a concentration which can be measured in the analysis accompanying the scattered light, while increasing the light amount and maintaining the analyzing accuracy.
