  • Patent number: 10667693
    Abstract: Aspects of the present disclosure provide systems, methods, devices, and computer-readable media for interference filter correction based on angle of incidence. In some examples, a sample emits an emission spectrum that is filtered by an emission filter to provide a transmission spectrum. The emission spectrum illuminates the emission filter at multiple angles of incidence. The angles of incidence result in a spectral shifting of the transmission spectrum. Based on this spectral shifting, the intensity of the transmission spectrum is corrected. An image corresponding to the corrected intensity of the transmission spectrum may be generated.
