  • Patent number: 9778165
    Abstract: Systems for collecting light (e.g., in a flow stream) are described. Light collection systems according to embodiments include: a mount having an orifice for receiving light, an adapter configured for attaching a camera to the mount and a fastener for attaching a lens to the distal end of the mount and a releasably attachable connecter that is configured for coupling to an orifice plate and an aligner that is configured to couple with an aligner on the mount and maintain optical alignment between the mount and connector. Methods for coupling a connector and a mount are also described. Systems and methods for measuring light emitted by a sample (e.g., in a flow stream) are also provided.
    Type: Grant

  • Patent number: 8992835
    Abstract: Provided herein are improved multi-way cell sorter systems and methods. For example, provided are systems and methods for the collection of cells that are sorted in multiple directions. The systems and methods allow for the construction of a multi-way sorter (e.g., a ten-way sorter in the space that currently only allows four-way sorting). In addition the device may actively sense the arrival of drops (with cells of interest) at a sample tube, and trigger an alarm when the drops' arrivals deviate from an expected pattern.
