Abstract: Provided are optical fiber alignment assemblies, comprising: a plurality of fiber channel members being arranged along a first vertical axis, each fiber channel member comprising a fiber channel configured to accommodate an optical fiber disposed therein, the plurality of fiber channels being parallel to one another, fiber channels adjacent to one another defining a spacing therebetween, the spacing being measured along the first vertical axis; a plurality of resilient members, a resilient member being disposed between adjacent fiber channel members; and an adjustment element, the adjustment element being configured to effect a force oriented along the first vertical axis, and the adjustment member being configured such that actuation of the adjustment member changes a compression of the plurality of resilient members so as to effect an essentially linear variation in the spacing between adjacent fiber channels. Also provided are related methods.

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.

Abstract: A sampling system is provided. The sampling system includes a housing. Mounted to the housing is a Hall effect sensor. A probe configured to contact a sample is inserted into the housing. The probe includes an elongated portion and a restorative spring inserted onto the elongated portion of the probe. The restorative spring provides sufficient restorative force to return the probe to a relaxed position. The Hall effect sensor is configured to sense a field strength generated by the proximity of the restorative spring of the probe in the extended position.
