1. A host structure comprising:
a compartment disposed at least partially within the host structure, the compartment being configured to reversibly engage with a fluidic optical cartridge, the compartment including an interlock feature configured to reversibly engage the fluidic optical cartridge, wherein the fluidic optical cartridge comprises: a fluidic structure that includes a channel through which objects can travel along respective paths during operation of the apparatus, the channel having at least one transparent wall; and at least one optical component configured to provide measurement light to the objects traveling through the channel, the output light emanating from the objects in response to the measurement light, the host structure further comprising a source of the measurement light; a waveguide configured to deliver measurement light to the compartment; a detector configured to receive output light emanating from the fluidic optical cartridge and to generate one or more electrical signals in response to the output light; and electronics to process the electrical signals from the detector. |
