  • Patent number: 11828697
    Abstract: A system for fluorescence activated cell sorting includes at least two excitation lasers having different orientations relative to an objective such that light from the at least two lasers passes through the objective and intersects a fluidic channel at different positions within an interrogation region. The fluidic channel directs a flow of a plurality of fluorescently labeled particles through the interrogation region. The system further includes at least one detector and at least one optical element that directs light emitted from the plurality of fluorescently labeled particles and transmitted through the objective to the at least one detector. The system may further include optics for generating and detecting side and forward scattered light. Methods for operating example systems to collect fluorescent, side scattered and forward scattered light from a plurality of particles are also described herein.

  • Publication number: 20190084010
    Abstract: A system for fluorescence activated cell sorting includes at least two excitation lasers and an objective that directs light from the at least two excitation lasers to a common point in an interrogation region of a fluidic channel. The fluidic channel directs a flow of a plurality of fluorescently labeled particles through the interrogation region. At least one modulator temporally multiplexes light from the at least two excitation lasers such that pulses of light from different lasers intersect the common point at different times. The system further includes at least one detector and at least one optical element that directs light emitted from the particles and transmitted through the objective to the at least one detector. The system may further include optics for generating and detecting side and forward scattered light. Methods for operating example systems to collect fluorescent, side scattered and forward scattered light are also described herein.
