Abstract
The present disclosure relates to a spectral sensor for detection of individual light-emitting particles. The sensor is comprising an array of photo-sensitive detectors for detecting light emitted by said individual light-emitting particles and a filter array comprising a plurality of different band-stop filters. The filter array is configured to transmit wavelengths in a detectable wavelength region to the array of photo-sensitive detectors, and wherein each band-stop filter is associated with one or more particular photo-sensitive detectors, and the plurality of different band-stop filters are configured to reflect different wavelength intervals within said detectable wavelength region so that each photo-sensitive detector of the array is configured to detect the wavelengths of the detectable wavelength region other than the reflected wavelength interval of the band-stop filter being associated with the photo-sensitive detector. The sensor is further comprising a processing unit in communication with said array of photo-sensitive detectors and configured for determining a spectral characteristic of an individual light-emitting particle based on the response from said array of photo-sensitive detectors.
