1. A flow cytometry system comprising:
a measurement location;
one or more adjustable mirror mounts, each mirror mount including a corresponding mirror; and
one or more lasers, wherein:
each laser of the one or more lasers is oriented so as to emit a corresponding laser beam towards the mirror of a corresponding one of the one or more adjustable mirror mounts,
the mirror of each adjustable mirror mount of the one or more adjustable mirror mounts that has one of the one or more laser beams directed thereat is oriented such that the laser beam directed thereat is reflected off of the reflection surface of that mirror and towards the measurement location,
the mirrors of at least some of the adjustable mirror mounts are dichroic mirrors, and
at least some of the adjustable mirror mounts with dichroic mirrors are positioned such that an axis that passes through those dichroic mirrors intersects with the measurement location.
