Abstract
Devices, systems and methods facilitate analyzing, identifying and sorting particles in fluids, including cytometry devices and techniques. The described techniques can be used in a variety of applications such as in chemical or biological testing and diagnostic measurements. One exemplary flow cytometry device includes a channel that is capable of conducting a fluid containing at least one particle and also capable of allowing light be transmitted to and from the channel. The flow cytometry device also includes a lens that is positioned between the channel and a color filter. The lens directs at least a portion of light transmitted from the channel to the color filter. The color filter includes a plurality of zones, where each zone is adapted to allow transmission of only a particular spectral range of light. The flow cytometry device further includes a detector configured to receive the light that is transmitted through the color filter.
