Optical detection system for flow cytometry
First Claim
1. A method for determining the scattering produced by one or more particles in a stream in a flow channel, the method comprising:
- activating a linear array of light sources to provide a substantially constant light intensity across a width of the flow channel;
receiving with a light detector the substantially constant light intensity provided across the width of the flow channel by the linear array of light sources; and
wherein the substantially constant light intensity provided across the width of the flow channel provides for consistent measurement accuracy across the width of the flow channel.

Abstract
An optical detection system for flow cytometry that uses two or more light sources positioned laterally at different distances from a central axis of a flow stream for providing light through different parts of the flow stream. One or more lenses are used to focus the light from the two or more light sources through the flow stream and onto a common focal point or region on the opposite side of the flow stream. One or more light detectors are then placed at, near or around the common focal point or region. A processor or the like receives at least one output signal from the one or more light detectors to analyze and determine selected characteristics of the flow stream.
