Abstract: A flow cytometer, laser optics assembly thereof, and methods of assembling the same are provided. The flow cytometer is capable of yielding consistent and accurate results despite exposure to adverse environmental conditions such as, for example, temperature changes within a relatively wide temperature range and/or a relatively large amount of random-axis mechanical vibration. The flow cytometer of the present disclosure is additionally or alternatively relatively insensitive to real or apparent core stream shifts, employs a slowly converging beam along the axis perpendicular to core stream flow, and provides the ability to precisely measure time-of-flight.

Abstract: A flow cytometer of a blood analyzer including a transverse-electric (TE) laser diode, a flow cell, a quarter wave plate (QWP), a plurality of lenses, and a side scatter detector. The TE laser diode is configured to output a laser beam along an optical axis and has a fast axis full width at half maximum (FWHM) divergence of from about 16 degrees to about 25 degrees. The QWP is disposed along the optical axis between the TE laser diode and the flow cell and configured to circularly polarize the laser beam. The plurality of lenses is disposed between the TE laser diode and the flow cell and configured to focus the laser beam at the flow cell.
