Abstract
A flow cytometer including a laser, indexing structure, adjustment structure, and sensor structure. The cytometer is conventionally used with a removable microfluidic cassette, which is installed at a first position that is enforced by the indexing structure. The adjustment structure changes a relative position between an interrogation aperture of the cassette and the laser beam. Feedback from the sensor structure is used to optimize propagation of the laser through the interrogation aperture to reduce (and hopefully eliminate) autofluorescence caused by beam impingement onto the cassette.
