Claim 14:
15. A flow cytometer of a blood analyzer, comprising:
a transverse-electric (TE) laser diode configured to output a laser beam along an optical axis, the laser beam having a fast axis full width at half maximum (FWHM) divergence of from about 16 degrees to about 25 degrees;
a flow cell;
a plurality of lenses disposed along the optical axis between the TE laser diode and the flow cell, the plurality of lenses cooperating to focus the laser beam at the flow cell; and
a side scatter detector configured to detect side-scattered light from the flow cell at angles of about 50 degrees to about 120 degrees relative to the optical axis.
