  • Patent number: 10481084
    Abstract: A spectroscopy system and method in which the optical path following the interferometer includes a Jacquinot stop having an aperture disposed substantially at its focal point. The Jacquinot stop includes a reflective surface substantially non-orthogonal to the longitudinal axis of the path and facing the source of the IR signal containing an interferogram. The aperture passes an inner portion of the incident IR signal, while the reflective surface reflects an outer portion. The reflected outer portion of the incident IR signal, which contains erroneous spectral information due to inherent flaws in the interferometer optics, is thereby effectively removed from the original incident IR signal ultimately used to irradiate the sample, and yet still be made available for use in monitoring background spectra of the sampling optics.

  • Patent number: 10481094
    Abstract: The present disclosure discloses a total internal reflection fluorescence imaging system and a sequencing device. The total internal reflection fluorescence imaging system includes a first imaging system and a second imaging system. The first imaging system includes N separate laser light paths. The second imaging system determines the changes of the height of the sample by means of the differences of the positions at which the second receiving device acquires the second images, and performs automatic compensation according to the changes of the height of the sample, so as to ensure that the sample is always at a focused position. The embodiment can perform light path adjustment of the N separate laser light paths respectively by means of the second imaging system, so as to realize that the N separate laser light paths have the same penetration depth. Therefore no further light path adjustment is required when switching between different light sources, thus saving the time consuming for light path adjustment.

  • Patent number: 10474002
    Abstract: In one aspect, a method is provided for generating supercontinuum laser pulses within a continuous mid-infrared spectral range in a chalcogenide material. This method includes focusing an input laser beam of femtosecond pulses with a pulse energy higher than 10 microjoule along an optical path of the input laser beam; placing a chalcogenide material at a selected location along the optical path of the laser beam so that the laser intensity at the chalcogenide material is sufficiently high to cause nonlinear optical absorption that causes conversion of input optical energy into supercontinuum laser pulses of a pulse energy at or above a microjoule level at optical wavelengths within a broad continuous mid-infrared spectral range without damaging the chalcogenide material; and simultaneously moving the chalcogenide material laterally relative to the input laser beam to avoid damage to the chalcogenide material.
