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.

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.
