Abstract
In an apparatus for analyzing a particle flowing in a flow section of a flow cell, at least two non-parallel index beams are projected onto the flow cell to detect a focusing state of a measuring optical system with respect to the flow section, the beams reflected by first and second walls of the flow cell are detected, and the obtained output pattern is used to determine the focusing state.
