  • Patent number: 10718663
    Abstract: An optical assembly is disclosed including two laterally variable bandpass optical filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. The lateral displacement may cause a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap. A photodetector array may be disposed downstream of the downstream filter. The optical assembly may be coupled via a variety of optical conduits or optical fibers for spectroscopic measurements of a flowing sample.

  • Patent number: 10690543
    Abstract: A system, method, and device for evaluating the intensity profile of a laser beam. The laser detection system has a target surface with an interior and an exterior. The target surface and a housing create a target pod with an enclosed interior chamber. A beacon is provided at the target pod to provide for targeting. A camera is provided that images the interior of the target surface from within the enclosed interior chamber. Some percentage of the intensity of the laser beam passes through the target surface uniformly and illuminates the interior of the target surface when the laser beam strikes the target surface. The illumination of and subsequent scattering from the interior of the target surface is imaged by the camera for analysis. By detecting the laser intensity as a function of position, the intensity profile of the laser beam can be quantified.

  • Patent number: 10337984
    Abstract: A measurement apparatus comprises optical components arranged to provide parallel measurements of a biological sample. The parallel sample measurements provide improved accuracy with lower detection limit thresholds. The parallel measurements may comprise one or more of Raman spectroscopy measurements or infrared spectroscopy measurements. The parallel measurements can be combined with a light source. In many embodiments, the light source comprises one or more wavelengths corresponding to resonance frequencies of one or more molecules of the sample, such as wavelengths of ultraviolet light. The wavelengths of light corresponding to resonance frequencies can provide an increased signal to noise ratio. The parallel array optical configuration can be combined with wavelengths of light corresponding to resonance frequencies in order to provide increased measurement accuracy and detection of metabolites.
