Abstract
A light source apparatus can avoid double-counting of particles in a flow cytometer for measuring and analyzing a plurality of particles flowing in a flow cell. A light source apparatus for a flow cytometer includes a semiconductor laser for emitting a laser beam, a collimating lens for collimating the laser beam emitted from the semiconductor laser in a spread light state, a first beam conversion unit composed of prisms and a second beam conversion unit composed of prisms for matching a flow cell length direction with a slow axis direction of the collimated laser beam in a flow cell after reducing the beam diameter in a fast axis direction and increasing the beam diameter in the slow axis direction, and a focusing lens for focusing the laser beam passed through these beam conversion units in the flow cell.
