Abstract
The present set of embodiments relate to a system, method, and apparatus for an optical configuration in a flow cytometer that allows for independent adjustment of focusing for each light source. Such systems, methods, and apparatuses require a final focusing element to be moved near the beginning of the optical train and for each optical element coming after the final focusing element to be configured to accommodate converging light beams while minimizing the introduction of aberrations into those beams.
Claims19
A system, comprising:
- a flow cell configured to receive a fluid sample, the flow cell having an interrogation zone;
- a first optical subunit comprising:
- (i) a first light source configured to produce a first light beam, and (ii) a first converging element configured to convert the first light beam into a first converging light beam;
- a second optical subunit comprising:
- (i) a second light source configured to produce a second light beam, and (ii) a second converging element configured to convert the second light beam into a second converging light beam;
- and
- an optical train comprising a dichroic element configured to direct the first and second converging light beams to the interrogation zone, wherein the first and second converging light beams are communicated directly from the dichroic element to the interrogation zone.
