  • Optical spectrometer modules, systems and methods for optical analysis with multiple light beams
    Patent number: 11703388
    Abstract: A method of optical analysis comprises receiving light at an optical spectrometer module from a light source, distributing the received light into two or more light beams with a light distribution component of the optical spectrometer module, concurrently exposing each of a reference and one or more test samples to one of the two or more light beams, and concurrently measuring a property of the light associated with each of the reference sample and one or more test samples with a corresponding detector.
    Type: Grant

    Date of Patent: July 18, 2023
    Assignee: Agilent Technologies, Inc.
    Inventors: Hugh Charles Stevenson, David Death, Eran Lande
  • Spectrophotometer calibration methods and systems
    Patent number: 11181422
    Abstract: A method of calibrating a spectrophotometer comprising a flash lamp. The method comprises receiving light from the flash lamp at a monochromator of the spectrometer, wherein the flash lamp is a short arc noble gas flash lamp with transverse or axially aligned electrodes; configuring the monochromator to progressively transmit the received light at each of a plurality wavelengths of a selected range of wavelengths, wherein the range of wavelengths is associated with a wavelength feature according to a known spectral profile of the flash lamp, and wherein the wavelength feature is a self-absorption feature; and determining a spectrum of the flash lamp, wherein the spectrum comprises a corresponding power or intensity value for each of the plurality of wavelengths.
